-;;; al.el --- Interface for working with associative lists -*- lexical-binding: t -*-
-
-;; Author: William Carroll <wpcarro@gmail.com>
-;; Version: 0.0.1
-;; Package-Requires: ((emacs "25.1"))
-
-;;; Commentary:
-;; Firstly, a rant:
-;; In most cases, I find Elisp's APIs to be confusing.  There's a mixture of
-;; overloaded functions that leak the implementation details (TODO: provide an
-;; example of this.) of the abstract data type, which I find privileges those
-;; "insiders" who spend disproportionately large amounts of time in Elisp land,
-;; and other functions with little-to-no pattern about the order in which
-;; arguments should be applied.  In theory, however, most of these APIs could
-;; and should be much simpler.  This module represents a step in that direction.
-;;
-;; I'm modelling these APIs after Elixir's APIs.
-;;
-;; On my wishlist is to create protocols that will allow generic interfaces like
-;; Enum protocols, etc.  Would be nice to abstract over...
-;; - associative lists (i.e. alists)
-;; - property lists (i.e. plists)
-;; - hash tables
-;; ...with some dictionary or map-like interface.  This will probably end up
-;; being quite similar to the kv.el project but with differences at the API
-;; layer.
-;;
-;; Similar libraries:
-;; - map.el: Comes bundled with recent versions of Emacs.
-;; - asoc.el: Helpers for working with alists.  asoc.el is similar to alist.el
-;;   because it uses the "!" convention for signalling that a function mutates
-;;   the underlying data structure.
-;; - ht.el: Hash table library.
-;; - kv.el: Library for dealing with key-value collections.  Note that map.el
-;;   has a similar typeclass because it works with lists, hash-tables, or
-;;   arrays.
-;; - a.el: Clojure-inspired way of working with key-value data structures in
-;; Elisp.  Works with alists, hash-tables, and sometimes vectors.
-;;
-;; Some API design principles:
-;; - The "noun" (i.e. alist) of the "verb" (i.e. function) comes last to improve
-;; composability with the threading macro (i.e. `->>') and to improve consumers'
-;; intuition with the APIs.  Learn this once, know it always.
-;;
-;; - Every function avoids mutating the alist unless it ends with !.
-;;
-;; - CRUD operations will be named according to the following table:
-;;   - "create" *and* "set"
-;;   - "read"   *and* "get"
-;;   - "update"
-;;   - "delete" *and* "remove"
-;;
-;; For better or worse, all of this code expects alists in the form of:
-;; ((first-name . "William") (last-name . "Carroll"))
-;;
-;; Special thanks to github.com/alphapapa/emacs-package-dev-handbook for some of
-;; the idiomatic ways to update alists.
-;;
-;; TODO: Include a section that compares alist.el to a.el from
-;; github.com/plexus/a.el.

-;;; list.el --- Functions for working with lists -*- lexical-binding: t -*-
-
-;; Author: William Carroll <wpcarro@gmail.com>
-;; Version: 0.0.1
-;; Package-Requires: ((emacs "24"))
-
-;;; Commentary:
-;; Since I prefer having the `list-' namespace, I wrote this module to wrap many
-;; of the functions that are defined in the the global namespace in ELisp.  I
-;; sometimes forget the names of these functions, so it's nice for them to be
-;; organized like this.
-;;
-;; Motivation:
-;; Here are some examples of function names that I cannot tolerate:
-;; - `car': Return the first element (i.e. "head") of a linked list
-;; - `cdr': Return the tail of a linked list
-
-;; As are most APIs for standard libraries that I write, this is heavily
-;; influenced by Elixir's standard library.
-;;
-;; Elixir's List library:
-;; - ++/2
-;; - --/2
-;; - hd/1
-;; - tl/1
-;; - in/2
-;; - length/1
-;;
-;; Similar libraries:
-;; - dash.el: Functional library that mimmicks Clojure.  It is consumed herein.
-;; - list-utils.el: Utility library that covers things that dash.el may not
-;;   cover.
-;;   stream.el: Elisp implementation of streams, "implemented as delayed
-;;   evaluation of cons cells."
-
-;; TODO: Consider naming this file linked-list.el.
-
-;; TODO: Support module-like macro that auto-namespaces functions.
-
-;; TODO: Consider wrapping most data structures like linked-lists,
-;; associative-lists, etc in a `cl-defstruct', so that the dispatching by type
-;; can be nominal instead of duck-typing.  I'm not sure if this is a good idea
-;; or not.  If I do this, I should provide isomorphisms to map between idiomatic
-;; ways of working with Elisp data structures and my wrapped variants.
-
-;; TODO: Are function aliases/synonyms even a good idea?  Or do they just
-;; bloat the API unnecessarily?

-;;; struct.el --- Helpers for working with structs -*- lexical-binding: t -*-
-
-;; Author: William Carroll <wpcarro@gmail.com>
-;; Version: 0.0.1
-;; Package-Requires: ((emacs "24.3"))
-
-;;; Commentary:
-;; Provides new macros for working with structs.  Also provides adapter
-;; interfaces to existing struct macros, that should have more intuitive
-;; interfaces.
-;;
-;; Sometimes `setf' just isn't enough.
