-# rule_haskell examples
-
-Examples of using [rules_haskell][rules_haskell], the Bazel rule set
-for building Haskell code.
-
-* [**vector:**](./vector/) shows how to build the `vector` package as
-  found on Hackage, using a Nix provided compiler toolchain.
-* [**rts:**](./rts/) demonstrates foreign exports and shows how to
-  link against GHC's RTS library, i.e. `libHSrts.so`.
-  
-## **Important**
-
-Run all commands from the root of `rules_haskell`.
-If you `cd examples/`, bazel *will* [break on
-you](https://github.com/tweag/rules_haskell/issues/740).
-This is a current problem with bazel workspaces.
-
-## Root Workspace
-
-Build everything in the root workspace with;
-
-```
-$ bazel build @io_tweag_rules_haskell_examples//...
-```
-
-Show every target of the vector example;
-
-```
-$ bazel query @io_tweag_rules_haskell_examples//vector/...

-@io_tweag_rules_haskell_examples//vector:ghc-prim
-@io_tweag_rules_haskell_examples//vector:deepseq
-@io_tweag_rules_haskell_examples//vector:base
-```
-
-Build the two main Haskell targets;
-
-```

-{- $namingConventions
-For historical reasons, this library embraces the practice of suffixing
-the name of a function with the type it operates on. For example, three
-of the variants of the array indexing function are:
-
-> indexArray      ::           Array      a -> Int -> a
-> indexSmallArray ::           SmallArray a -> Int -> a
-> indexPrimArray  :: Prim a => PrimArray  a -> Int -> a
-
-In a few places, where the language sounds more natural, the array type
-is instead used as a prefix. For example, @Data.Primitive.SmallArray@
-exports @smallArrayFromList@, which would sound unnatural if it used
-@SmallArray@ as a suffix instead.
-
-This library provides several functions traversing, building, and filtering
-arrays. These functions are suffixed with an additional character to
-indicate their the nature of their effectfulness:
-
-* No suffix: A non-effectful pass over the array.
-* @-A@ suffix: An effectful pass over the array, where the effect is 'Applicative'.
-* @-P@ suffix: An effectful pass over the array, where the effect is 'PrimMonad'.
-
-Additionally, an apostrophe can be used to indicate strictness in the elements.
-The variants with an apostrophe are used in @Data.Primitive.Array@ but not
-in @Data.Primitive.PrimArray@ since the array type it provides is always strict in the element.
-For example, there are three variants of the function that filters elements
-from a primitive array.
-
-> filterPrimArray  :: (Prim a               ) => (a ->   Bool) -> PrimArray a ->    PrimArray a
-> filterPrimArrayA :: (Prim a, Applicative f) => (a -> f Bool) -> PrimArray a -> f (PrimArray a)
-> filterPrimArrayP :: (Prim a, PrimMonad   m) => (a -> m Bool) -> PrimArray a -> m (PrimArray a)
-
-As long as the effectful context is a monad that is sufficiently affine
-the behaviors of the 'Applicative' and 'PrimMonad' variants produce the same results
-and differ only in their strictness. Monads that are sufficiently affine
-include:
-
-* 'IO' and 'ST'
-* Any combination of 'MaybeT', 'ExceptT', 'StateT' and 'Writer' on top
-  of another sufficiently affine monad.
-
-There is one situation where the names deviate from effectful suffix convention
-described above. Throughout the haskell ecosystem, the 'Applicative' variant of
-'map' is known as 'traverse', not @mapA@. Consequently, we adopt the following
-naming convention for mapping:
-
-> mapPrimArray :: (Prim a, Prim b) => (a -> b) -> PrimArray a -> PrimArray b
-> traversePrimArray :: (Applicative f, Prim a, Prim b) => (a -> f b) -> PrimArray a -> f (PrimArray b)
-> traversePrimArrayP :: (PrimMonad m, Prim a, Prim b) => (a -> m b) -> PrimArray a -> m (PrimArray b)

--- | Traverse a primitive array. The traversal forces the resulting values and

--- Consequently:
---
--- >>> traversePrimArrayP (\x -> print x $> bool x undefined (x == 2)) (fromList [1, 2, 3 :: Int])
--- 1
--- 2
--- *** Exception: Prelude.undefined
---
--- In many situations, 'traversePrimArrayP' can replace 'traversePrimArray',
--- changing the strictness characteristics of the traversal but typically improving
--- the performance. Consider the following short-circuiting traversal:
---
--- > incrPositiveA :: PrimArray Int -> Maybe (PrimArray Int)
--- > incrPositiveA xs = traversePrimArray (\x -> bool Nothing (Just (x + 1)) (x > 0)) xs
---
--- This can be rewritten using 'traversePrimArrayP'. To do this, we must
--- change the traversal context to @MaybeT (ST s)@, which has a 'PrimMonad'
--- instance:
---
--- > incrPositiveB :: PrimArray Int -> Maybe (PrimArray Int)
--- > incrPositiveB xs = runST $ runMaybeT $ traversePrimArrayP
--- >   (\x -> bool (MaybeT (return Nothing)) (MaybeT (return (Just (x + 1)))) (x > 0))
--- >   xs
--- 
--- Benchmarks demonstrate that the second implementation runs 150 times
--- faster than the first. It also results in fewer allocations.

--- Module : Data.Primitive.SmallArray
--- Copyright: (c) 2015 Dan Doel
--- License: BSD3
---
--- Maintainer: libraries@haskell.org
--- Portability: non-portable
---
--- Small arrays are boxed (im)mutable arrays.
---
--- The underlying structure of the 'Array' type contains a card table, allowing
--- segments of the array to be marked as having been mutated. This allows the
--- garbage collector to only re-traverse segments of the array that have been
--- marked during certain phases, rather than having to traverse the entire
--- array.
---
--- 'SmallArray' lacks this table. This means that it takes up less memory and
--- has slightly faster writes. It is also more efficient during garbage
--- collection so long as the card table would have a single entry covering the
--- entire array. These advantages make them suitable for use as arrays that are
--- known to be small.
---
--- The card size is 128, so for uses much larger than that, 'Array' would likely
--- be superior.
---
--- The underlying type, 'SmallArray#', was introduced in GHC 7.10, so prior to
--- that version, this module simply implements small arrays as 'Array'.

--- in GHC 8.6 and up. For example, consider a user-defined 'Prim' instance for
--- a multi-word data type.
---
--- > data Uuid = Uuid Word64 Word64
--- >   deriving Storable via (PrimStorable Uuid)
--- > instance Prim Uuid where ...
---
--- Writing the 'Prim' instance is tedious and unavoidable, but the 'Storable'
--- instance comes for free once the 'Prim' instance is written.

--- Module      : Data.Primitive.UnliftedArray
--- Copyright   : (c) Dan Doel 2016
--- License     : BSD-style
---
--- Maintainer  : Libraries <libraries@haskell.org>
--- Portability : non-portable
---
--- GHC contains three general classes of value types:
---
---   1. Unboxed types: values are machine values made up of fixed numbers of bytes
---   2. Unlifted types: values are pointers, but strictly evaluated
---   3. Lifted types: values are pointers, lazily evaluated
---
--- The first category can be stored in a 'ByteArray', and this allows types in
--- category 3 that are simple wrappers around category 1 types to be stored
--- more efficiently using a 'ByteArray'. This module provides the same facility
--- for category 2 types.
---
--- GHC has two primitive types, 'ArrayArray#' and 'MutableArrayArray#'. These
--- are arrays of pointers, but of category 2 values, so they are known to not
--- be bottom. This allows types that are wrappers around such types to be stored
--- in an array without an extra level of indirection.
---
--- The way that the 'ArrayArray#' API works is that one can read and write
--- 'ArrayArray#' values to the positions. This works because all category 2
--- types share a uniform representation, unlike unboxed values which are
--- represented by varying (by type) numbers of bytes. However, using the
--- this makes the internal API very unsafe to use, as one has to coerce values
--- to and from 'ArrayArray#'.
---
--- The API presented by this module is more type safe. 'UnliftedArray' and
--- 'MutableUnliftedArray' are parameterized by the type of arrays they contain, and
--- the coercions necessary are abstracted into a class, 'PrimUnlifted', of things
--- that are eligible to be stored.

-## Changes in version 0.6.4.0
-
- * Introduce `Data.Primitive.PrimArray`, which offers types and function
-   for dealing with a `ByteArray` tagged with a phantom type variable for
-   tracking the element type.
-
- * Implement `isByteArrayPinned` and `isMutableByteArrayPinned`.
-
- * Add `Eq1`, `Ord1`, `Show1`, and `Read1` instances for `Array` and
-   `SmallArray`.
-
- * Improve the test suite. This includes having property tests for
-   typeclasses from `base` such as `Eq`, `Ord`, `Functor`, `Applicative`,
-   `Monad`, `IsList`, `Monoid`, `Foldable`, and `Traversable`.
-
- * Fix the broken `IsList` instance for `ByteArray`. The old definition
-   would allocate a byte array of the correct size and then leave the
-   memory unitialized instead of writing the list elements to it.
-
- * Fix the broken `Functor` instance for `Array`. The old definition
-   would allocate an array of the correct size with thunks for erroring
-   installed at every index. It failed to replace these thunks with
-   the result of the function applied to the elements of the argument array.
-
- * Fix the broken `Applicative` instances of `Array` and `SmallArray`.
-   The old implementation of `<*>` for `Array` failed to initialize
-   some elements but correctly initialized others in the resulting
-   `Array`. It is unclear what the old behavior of `<*>` was for
-   `SmallArray`, but it was incorrect.
-
- * Fix the broken `Monad` instances for `Array` and `SmallArray`.
-
- * Fix the implementation of `foldl1` in the `Foldable` instances for
-   `Array` and `SmallArray`. In both cases, the old implementation
-   simply returned the first element of the array and made no use of
-   the other elements in the array.
-
- * Fix the implementation of `mconcat` in the `Monoid` instance for
-   `SmallArray`.
- 
- * Implement `Data.Primitive.Ptr`, implementations of `Ptr` functions
-   that require a `Prim` constraint instead of a `Storable` constraint.
-
-
- * Add `PrimUnlifted` instances for `TVar` and `MVar`.
-
- * Use `compareByteArrays#` for the `Eq` and `Ord` instances of
-   `ByteArray` when building with GHC 8.4 and newer.
-
- * Add `Prim` instances for lots of types in `Foreign.C.Types` and
-   `System.Posix.Types`.
-
- * Reexport `Data.Primitive.SmallArray` and `Data.Primitive.UnliftedArray`
-   from `Data.Primitive`.
-
- * Add fold functions and map function to `Data.Primitive.UnliftedArray`.
-   Add typeclass instances for `IsList`, `Ord`, and `Show`.
-
- * Add `defaultSetByteArray#` and `defaultSetOffAddr#` to
-   `Data.Primitive.Types`.
-
-## Changes in version 0.6.3.0
-
- * Add `PrimMonad` instances for `ContT`, `AccumT`, and `SelectT` from
-   `transformers`
-
- * Add `Eq`, `Ord`, `Show`, and `IsList` instances for `ByteArray`
-
- * Add `Semigroup` instances for `Array` and `SmallArray`. This allows
-   `primitive` to build on GHC 8.4 and later.
-
-## Changes in version 0.6.2.0
-
- * Drop support for GHCs before 7.4
-
- * `SmallArray` support
-
- * `ArrayArray#` based support for more efficient arrays of unlifted pointer types
-
- * Make `Array` and the like instances of various classes for convenient use
-
- * Add `Prim` instances for Ptr and FunPtr
-
- * Add `ioToPrim`, `stToPrim` and unsafe counterparts for situations that would
-   otherwise require type ascriptions on `primToPrim`
-
- * Add `evalPrim`
-
- * Add `PrimBase` instance for `IdentityT`
-
-## Changes in version 0.6.1.0
-
- * Use more appropriate types in internal memset functions, which prevents
-   overflows/segfaults on 64-bit systems.
-
- * Fixed a warning on GHC 7.10
-
- * Worked around a -dcore-lint bug in GHC 7.6/7.7
-
-## Changes in version 0.6
-
- * Split PrimMonad into two classes to allow automatic lifting of primitive
-   operations into monad transformers. The `internal` operation has moved to the
-   `PrimBase` class.
-
- * Fixed the test suite on older GHCs
-
-## Changes in version 0.5.4.0
-
- * Changed primitive_ to work around an oddity with GHC's code generation
-   on certain versions that led to side effects not happening when used
-   in conjunction with certain very unsafe IO performers.
-
- * Allow primitive to build on GHC 7.9
-
-## Changes in version 0.5.3.0
-
- * Implement `cloneArray` and `cloneMutableArray` primitives
-   (with fall-back implementations for GHCs prior to version 7.2.1)
-
-## Changes in version 0.5.2.1
-
- * Add strict variants of `MutVar` modification functions
-   `atomicModifyMutVar'` and `modifyMutVar'`
-
- * Fix compilation on Solaris 10 with GNU C 3.4.3
-
-## Changes in version 0.5.1.0
-
- * Add support for GHC 7.7's new primitive `Bool` representation
-
-## Changes in version 0.5.0.1
-
- * Disable array copying primitives for GHC 7.6.* and earlier
-
-## Changes in version 0.5
-
- * New in `Data.Primitive.MutVar`: `atomicModifyMutVar`
-
- * Efficient block fill operations: `setByteArray`, `setAddr`
-
-## Changes in version 0.4.1
-
- * New module `Data.Primitive.MutVar`
-
-## Changes in version 0.4.0.1
-
- * Critical bug fix in `fillByteArray`
-
-## Changes in version 0.4
-
- * Support for GHC 7.2 array copying primitives
-
- * New in `Data.Primitive.ByteArray`: `copyByteArray`,
-   `copyMutableByteArray`, `moveByteArray`, `fillByteArray`
-
- * Deprecated in `Data.Primitive.ByteArray`: `memcpyByteArray`,
-   `memcpyByteArray'`, `memmoveByteArray`, `memsetByteArray`
-
- * New in `Data.Primitive.Array`: `copyArray`, `copyMutableByteArray`
-
- * New in `Data.Primitive.Addr`: `copyAddr`, `moveAddr`
-
- * Deprecated in `Data.Primitive.Addr`: `memcpyAddr`

-
-{- $conventions
-Most monad transformer modules include the special case of applying
-the transformer to 'Data.Functor.Identity.Identity'.  For example,
-@'Control.Monad.Trans.State.Lazy.State' s@ is an abbreviation for
-@'Control.Monad.Trans.State.Lazy.StateT' s 'Data.Functor.Identity.Identity'@.
-
-Each monad transformer also comes with an operation @run@/XXX/@T@ to
-unwrap the transformer, exposing a computation of the inner monad.
-(Currently these functions are defined as field labels, but in the next
-major release they will be separate functions.)
-
-All of the monad transformers except 'Control.Monad.Trans.Cont.ContT'
-and 'Control.Monad.Trans.Cont.SelectT' are functors on the category
-of monads: in addition to defining a mapping of monads, they
-also define a mapping from transformations between base monads to
-transformations between transformed monads, called @map@/XXX/@T@.
-Thus given a monad transformation @t :: M a -> N a@, the combinator
-'Control.Monad.Trans.State.Lazy.mapStateT' constructs a monad
-transformation
-
-> mapStateT t :: StateT s M a -> StateT s N a
-
-For these monad transformers, 'lift' is a natural transformation in the
-category of monads, i.e. for any monad transformation @t :: M a -> N a@,
-
-* @map@/XXX/@T t . 'lift' = 'lift' . t@
-
-Each of the monad transformers introduces relevant operations.
-In a sequence of monad transformers, most of these operations.can be
-lifted through other transformers using 'lift' or the @map@/XXX/@T@
-combinator, but a few with more complex type signatures require
-specialized lifting combinators, called @lift@/Op/
-(see "Control.Monad.Signatures").
--}
-
-{- $strict
-
-A monad is said to be /strict/ if its '>>=' operation is strict in its first
-argument.  The base monads 'Maybe', @[]@ and 'IO' are strict:
-
->>> undefined >> return 2 :: Maybe Integer
-*** Exception: Prelude.undefined
-
-However the monad 'Data.Functor.Identity.Identity' is not:
-
->>> runIdentity (undefined >> return 2)
-2
-
-In a strict monad you know when each action is executed, but the monad
-is not necessarily strict in the return value, or in other components
-of the monad, such as a state.  However you can use 'seq' to create
-an action that is strict in the component you want evaluated.
--}
-
-{- $example1
-
-The first example is a parser monad in the style of
-
-* \"Monadic parsing in Haskell\", by Graham Hutton and Erik Meijer,
-/Journal of Functional Programming/ 8(4):437-444, July 1998
-(<http://www.cs.nott.ac.uk/~pszgmh/bib.html#pearl>).
-
-We can define such a parser monad by adding a state (the 'String' remaining
-to be parsed) to the @[]@ monad, which provides non-determinism:
-
-> import Control.Monad.Trans.State
->
-> type Parser = StateT String []
-
-Then @Parser@ is an instance of @MonadPlus@: monadic sequencing implements
-concatenation of parsers, while @mplus@ provides choice.  To use parsers,
-we need a primitive to run a constructed parser on an input string:
-
-> runParser :: Parser a -> String -> [a]
-> runParser p s = [x | (x, "") <- runStateT p s]
-
-Finally, we need a primitive parser that matches a single character,
-from which arbitrarily complex parsers may be constructed:
-
-> item :: Parser Char
-> item = do
->     c:cs <- get
->     put cs
->     return c
-
-In this example we use the operations @get@ and @put@ from
-"Control.Monad.Trans.State", which are defined only for monads that are
-applications of 'Control.Monad.Trans.State.Lazy.StateT'.  Alternatively one
-could use monad classes from the @mtl@ package or similar, which contain
-methods @get@ and @put@ with types generalized over all suitable monads.
--}
-
-{- $example2
-
-We can define a parser that also counts by adding a
-'Control.Monad.Trans.Writer.Lazy.WriterT' transformer:
-
-> import Control.Monad.Trans.Class
-> import Control.Monad.Trans.State
-> import Control.Monad.Trans.Writer
-> import Data.Monoid
->
-> type Parser = WriterT (Sum Int) (StateT String [])
-
-The function that applies a parser must now unwrap each of the monad
-transformers in turn:
-
-> runParser :: Parser a -> String -> [(a, Int)]
-> runParser p s = [(x, n) | ((x, Sum n), "") <- runStateT (runWriterT p) s]
-
-To define the @item@ parser, we need to lift the
-'Control.Monad.Trans.State.Lazy.StateT' operations through the
-'Control.Monad.Trans.Writer.Lazy.WriterT' transformer.
-
-> item :: Parser Char
-> item = do
->     c:cs <- lift get
->     lift (put cs)
->     return c
-
-In this case, we were able to do this with 'lift', but operations with
-more complex types require special lifting functions, which are provided
-by monad transformers for which they can be implemented.  If you use the
-monad classes of the @mtl@ package or similar, this lifting is handled
-automatically by the instances of the classes, and you need only use
-the generalized methods @get@ and @put@.
-
-We can also define a primitive using the Writer:
-
-> tick :: Parser ()
-> tick = tell (Sum 1)
-
-Then the parser will keep track of how many @tick@s it executes.
--}
-
-{- $example3
-
-This example is a cut-down version of the one in
-
-* \"Monad Transformers and Modular Interpreters\",
-by Sheng Liang, Paul Hudak and Mark Jones in /POPL'95/
-(<http://web.cecs.pdx.edu/~mpj/pubs/modinterp.html>).
-
-Suppose we want to define an interpreter that can do I\/O and has
-exceptions, an environment and a modifiable store.  We can define
-a monad that supports all these things as a stack of monad transformers:
-
-> import Control.Monad.Trans.Class
-> import Control.Monad.Trans.State
-> import qualified Control.Monad.Trans.Reader as R
-> import qualified Control.Monad.Trans.Except as E
-> import Control.Monad.IO.Class
->
-> type InterpM = StateT Store (R.ReaderT Env (E.ExceptT Err IO))
-
-for suitable types @Store@, @Env@ and @Err@.
-
-Now we would like to be able to use the operations associated with each
-of those monad transformers on @InterpM@ actions.  Since the uppermost
-monad transformer of @InterpM@ is 'Control.Monad.Trans.State.Lazy.StateT',
-it already has the state operations @get@ and @set@.
-
-The first of the 'Control.Monad.Trans.Reader.ReaderT' operations,
-'Control.Monad.Trans.Reader.ask', is a simple action, so we can lift it
-through 'Control.Monad.Trans.State.Lazy.StateT' to @InterpM@ using 'lift':
-
-> ask :: InterpM Env
-> ask = lift R.ask
-
-The other 'Control.Monad.Trans.Reader.ReaderT' operation,
-'Control.Monad.Trans.Reader.local', has a suitable type for lifting
-using 'Control.Monad.Trans.State.Lazy.mapStateT':
-
-> local :: (Env -> Env) -> InterpM a -> InterpM a
-> local f = mapStateT (R.local f)
-
-We also wish to lift the operations of 'Control.Monad.Trans.Except.ExceptT'
-through both 'Control.Monad.Trans.Reader.ReaderT' and
-'Control.Monad.Trans.State.Lazy.StateT'.  For the operation
-'Control.Monad.Trans.Except.throwE', we know @throwE e@ is a simple
-action, so we can lift it through the two monad transformers to @InterpM@
-with two 'lift's:
-
-> throwE :: Err -> InterpM a
-> throwE e = lift (lift (E.throwE e))
-
-The 'Control.Monad.Trans.Except.catchE' operation has a more
-complex type, so we need to use the special-purpose lifting function
-@liftCatch@ provided by most monad transformers.  Here we use
-the 'Control.Monad.Trans.Reader.ReaderT' version followed by the
-'Control.Monad.Trans.State.Lazy.StateT' version:
-
-> catchE :: InterpM a -> (Err -> InterpM a) -> InterpM a
-> catchE = liftCatch (R.liftCatch E.catchE)
-
-We could lift 'IO' actions to @InterpM@ using three 'lift's, but @InterpM@
-is automatically an instance of 'Control.Monad.IO.Class.MonadIO',
-so we can use 'Control.Monad.IO.Class.liftIO' instead:
-
-> putStr :: String -> InterpM ()
-> putStr s = liftIO (Prelude.putStr s)

--- This monad transformer adds the ability to fail or throw exceptions
--- to a monad.
---
--- A sequence of actions succeeds, producing a value, only if all the
--- actions in the sequence are successful.  If one fails with an error,
--- the rest of the sequence is skipped and the composite action fails
--- with that error.
---
--- If the value of the error is not required, the variant in
--- "Control.Monad.Trans.Maybe" may be used instead.
---
--- /Note:/ This module will be removed in a future release.
--- Instead, use "Control.Monad.Trans.Except", which does not restrict
--- the exception type, and also includes a base exception monad.

--- A sequence of actions terminates normally, producing a value,
--- only if none of the actions in the sequence throws an exception.
--- If one throws an exception, the rest of the sequence is skipped and
--- the composite action exits with that exception.
---
--- If the value of the exception is not required, the variant in
--- "Control.Monad.Trans.Maybe" may be used instead.

--- This version is strict; for a lazy version with the same interface,

--- Although the output is built strictly, it is not possible to
--- achieve constant space behaviour with this transformer: for that,

--- Strict state monads, passing an updatable state through a computation.
--- See below for examples.
---
--- Some computations may not require the full power of state transformers:
---
--- * For a read-only state, see "Control.Monad.Trans.Reader".
---
--- * To accumulate a value without using it on the way, see
---   "Control.Monad.Trans.Writer".
---
--- In this version, sequencing of computations is strict (but computations
--- are not strict in the state unless you force it with 'seq' or the like).
--- For a lazy version with the same interface, see

---
--- This version builds its output strictly; for a lazy version with

--- The identity functor and monad.
---
--- This trivial type constructor serves two purposes:
---
--- * It can be used with functions parameterized by functor or monad classes.
---
--- * It can be used as a base monad to which a series of monad
---   transformers may be applied to construct a composite monad.
---   Most monad transformer modules include the special case of
---   applying the transformer to 'Identity'.  For example, @State s@
---   is an abbreviation for @StateT s 'Identity'@.

-synopsis:     Concrete functor and monad transformers
-description:
-    A portable library of functor and monad transformers, inspired by
-    the paper
-    .
-    * \"Functional Programming with Overloading and Higher-Order
-    Polymorphism\", by Mark P Jones,
-    in /Advanced School of Functional Programming/, 1995
-    (<http://web.cecs.pdx.edu/~mpj/pubs/springschool.html>).
-    .
-    This package contains:
-    .
-    * the monad transformer class (in "Control.Monad.Trans.Class")
-    .
-    * concrete functor and monad transformers, each with associated
-      operations and functions to lift operations associated with other
-      transformers.
-    .
-    The package can be used on its own in portable Haskell code, in
-    which case operations need to be manually lifted through transformer
-    stacks (see "Control.Monad.Trans.Class" for some examples).
-    Alternatively, it can be used with the non-portable monad classes in
-    the @mtl@ or @monads-tf@ packages, which automatically lift operations
-    introduced by monad transformers through other transformers.

--- A library for boxed vectors (that is, polymorphic arrays capable of

---
---  * mutable
---
---  * immutable
---
--- and support a rich interface of both list-like operations, and bulk
--- array operations.

--- Monadic indexing
--- ----------------
-
--- | /O(1)/ Indexing in a monad.
---
--- The monad allows operations to be strict in the vector when necessary.
--- Suppose vector copying is implemented like this:
---
--- > copy mv v = ... write mv i (v ! i) ...
---
--- For lazy vectors, @v ! i@ would not be evaluated which means that @mv@
--- would unnecessarily retain a reference to @v@ in each element written.
---
--- With 'indexM', copying can be implemented like this instead:
---
--- > copy mv v = ... do
--- >                   x <- indexM v i
--- >                   write mv i x
---
--- Here, no references to @v@ are retained because indexing (but /not/ the
--- elements) is evaluated eagerly.

--- Monadic indexing
--- ----------------
-
--- | /O(1)/ Indexing in a monad.
---
--- The monad allows operations to be strict in the vector when necessary.
--- Suppose vector copying is implemented like this:
---
--- > copy mv v = ... write mv i (v ! i) ...
---
--- For lazy vectors, @v ! i@ would not be evaluated which means that @mv@
--- would unnecessarily retain a reference to @v@ in each element written.
---
--- With 'indexM', copying can be implemented like this instead:
---
--- > copy mv v = ... do
--- >                   x <- indexM v i
--- >                   write mv i x
---
--- Here, no references to @v@ are retained because indexing (but /not/ the
--- elements) is evaluated eagerly.

--- Monadic indexing
--- ----------------
-
--- | /O(1)/ Indexing in a monad.
---
--- The monad allows operations to be strict in the vector when necessary.
--- Suppose vector copying is implemented like this:
---
--- > copy mv v = ... write mv i (v ! i) ...
---
--- For lazy vectors, @v ! i@ would not be evaluated which means that @mv@
--- would unnecessarily retain a reference to @v@ in each element written.
---
--- With 'indexM', copying can be implemented like this instead:
---
--- > copy mv v = ... do
--- >                   x <- indexM v i
--- >                   write mv i x
---
--- Here, no references to @v@ are retained because indexing (but /not/ the
--- elements) is evaluated eagerly.

--- Monadic indexing
--- ----------------
-
--- | /O(1)/ Indexing in a monad.
---
--- The monad allows operations to be strict in the vector when necessary.
--- Suppose vector copying is implemented like this:
---
--- > copy mv v = ... write mv i (v ! i) ...
---
--- For lazy vectors, @v ! i@ would not be evaluated which means that @mv@
--- would unnecessarily retain a reference to @v@ in each element written.
---
--- With 'indexM', copying can be implemented like this instead:
---
--- > copy mv v = ... do
--- >                   x <- indexM v i
--- >                   write mv i x
---
--- Here, no references to @v@ are retained because indexing (but /not/ the
--- elements) is evaluated eagerly.

--- Adaptive unboxed vectors. The implementation is based on type families
--- and picks an efficient, specialised representation for every element type.
--- In particular, unboxed vectors of pairs are represented as pairs of unboxed
--- vectors.
---
--- Implementing unboxed vectors for new data types can be very easy. Here is
--- how the library does this for 'Complex' by simply wrapping vectors of
--- pairs.

--- Monadic indexing
--- ----------------
-
--- | /O(1)/ Indexing in a monad.
---
--- The monad allows operations to be strict in the vector when necessary.
--- Suppose vector copying is implemented like this:
---
--- > copy mv v = ... write mv i (v ! i) ...
---
--- For lazy vectors, @v ! i@ would not be evaluated which means that @mv@
--- would unnecessarily retain a reference to @v@ in each element written.
---
--- With 'indexM', copying can be implemented like this instead:
---
--- > copy mv v = ... do
--- >                   x <- indexM v i
--- >                   write mv i x
---
--- Here, no references to @v@ are retained because indexing (but /not/ the
--- elements) is evaluated eagerly.

-Category:       Data, Data Structures

-Synopsis:       Efficient Arrays

-Description:

-        .

-        An efficient implementation of Int-indexed arrays (both mutable

-        and immutable), with a powerful loop optimisation framework .

-        .

-        It is structured as follows:

-        .

-        ["Data.Vector"] Boxed vectors of arbitrary types.

-        .

-        ["Data.Vector.Unboxed"] Unboxed vectors with an adaptive

-        representation based on data type families.

-        .

-        ["Data.Vector.Storable"] Unboxed vectors of 'Storable' types.

-        .

-        ["Data.Vector.Primitive"] Unboxed vectors of primitive types as

-        defined by the @primitive@ package. "Data.Vector.Unboxed" is more

-        flexible at no performance cost.

-        .

-        ["Data.Vector.Generic"] Generic interface to the vector types.

-        .

-        There is also a (draft) tutorial on common uses of vector.

-        .

-        * <http://haskell.org/haskellwiki/Numeric_Haskell:_A_Vector_Tutorial>
