-;;; struct.el --- Helpers for working with structs -*- lexical-binding: t -*-
-;; Author: William Carroll <wpcarro@gmail.com>
-
-;;; 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.

-;; - TODO: Replace `symbol-name' and `intern' calls with isomorphism.
