-;;; maybe.el --- Library for dealing with nil values -*- lexical-binding: t -*-
-;; Author: William Carroll <wpcarro@gmail.com>
-
-;;; Commentary:
-;; Inspired by Elm's Maybe library.
-;;
-;; For now, a Nothing value will be defined exclusively as a nil value.  I'm
-;; uninterested in supported falsiness in this module even at risk of going
-;; against the LISP grain.
-;;
-;; I'm avoiding introducing a struct to handle the creation of Just and Nothing
-;; variants of Maybe.  Perhaps this is a mistake in which case this file would
-;; be more aptly named nil.el.  I may change that.  Because of this limitation,
-;; functions in Elm's Maybe library like andThen, which is the monadic bind for
-;; the Maybe type, doesn't have a home here since we cannot compose multiple
-;; Nothing or Just values without a struct or some other construct.
-;;
-;; Possible names for the variants of a Maybe.
-;; None    | Some
-;; Nothing | Something
-;; None    | Just
-;; Nil     | Set
-;;
-;; NOTE: In Elisp, values like '() (i.e. the empty list) are aliases for nil.
-;; What else in Elisp is an alias in this way?
-;; Examples:
-;; TODO: Provide examples of other nil types in Elisp.
