;;; private/erlang/config.el -*- lexical-binding: t; -*-
Major refactor & optimization of how modules load their packages Now that we are loading package autoloads files (as part of the generated doom-package-autoload-file when running make autoloads), many :commands properties are redundant. In fact, many def-package! blocks are redundant. In some cases, we can do without a config.el file entirely, and can move into the autoloads file or rely entirely on package autoloads. Also, many settings have been moved in their module's autoloads files, which makes them available ASAP; their use no longer depends on module load order. This gained me a modest ~10% boost in startup speed.

Refactor out map.el usage After some profiling, it turns out map-put and map-delete are 5-7x slower (more on Emacs 25) than delq, setf/alist-get and add-to-list for small lists (under 250 items), which is exactly how I've been using them. The only caveat is alist-get's signature is different on Emacs 25, thus a polyfill is necessary in core-lib.
