-;;; cache.el --- Caching things -*- lexical-binding: t -*-
-
-;; Author: William Carroll <wpcarro@gmail.com>
-;; Version: 0.0.1
-;; Package-Requires: ((emacs "24.3"))
-
-;;; Commentary:
-;; An immutable cache data structure.
-;;
-;; This is like a sideways stack, that you can pull values out from and re-push
-;; to the top.  It'd be like a stack supporting push, pop, pull.
-;;
-;; This isn't a key-value data-structure like you might expect from a
-;; traditional cache.  The name is subject to change, but the underlying idea of
-;; a cache remains the same.
-;;
-;; Think about prescient.el, which uses essentially an LRU cache integrated into
-;; counsel to help create a "clairovoyant", self-organizing list.
-;;
-;; Use-cases:
-;; - Keeps an cache of workspaces sorted as MRU with an LRU eviction strategy.

-;; Classifications of numbers:
-;; - Natural: (a.k.a positive integers, counting numbers); {1, 2, 3, ... }
-;;
-;; - Whole: Natural Numbers, plus zero; {0, 1, 2, 3, ...}
-;;
-;; - Integers: Whole numbers plus all the negatives of the natural numbers;
-;;   {... , -2, -1, 0, 1, 2, ...}
-;;
-;; - Rational numbers: (a.k.a. fractions) where the top and bottom numbers are
-;;   integers; e.g., 1/2, 3/4, 7/2, ⁻4/3, 4/1.  Note: The denominator cannot be
-;;   0, but the numerator can be.
-;;
-;; - Real numbers: All numbers that can be written as a decimal.  This includes
-;;   fractions written in decimal form e.g., 0.5, 0.75 2.35, ⁻0.073, 0.3333, or
-;;   2.142857. It also includes all the irrational numbers such as π, √2 etc.
-;;   Every real number corresponds to a point on the number line.
-;;
-;; The functions defined herein attempt to capture the mathematical definitions
-;; of numbers and their classifications as defined above.

-;;; sequence.el --- Working with the "sequence" types -*- lexical-binding: t -*-
-
-;; Author: William Carroll <wpcarro@gmail.com>
-;; Version: 0.0.1
-;; Package-Requires: ((emacs "25.1"))
-
-;;; Commentary:
-;; Elisp supports a typeclass none as "sequence" which covers the following
-;; types:
-;; - list: '(1 2 3 4 5)
-;; - vector: ["John" 27 :blue]
-;; - string: "To be or not to be..."
-
-;; TODO: Document the difference between a "reduce" and a "fold".  I.e. - reduce
-;; has an initial value whereas fold uses the first element in the sequence as
-;; the initial value.
-;;
-;; Note: This should be an approximation of Elixir's Enum protocol albeit
-;; without streams.
-;;
-;; Elisp has done a lot of this work already and these are mostly wrapper
-;; functions.
-;; See the following list for reference:
-;; - sequencep
-;; - elt
-;; - copy-sequence
-;; - reverse
-;; - nreverse
-;; - sort
-;; - seq-elt
-;; - seq-length
