In the case of snippet conflicts, you'd normally be prompted to select
which snippet you want. Built-in snippets are now disregarded if
conflicting private ones exist.
This makes it easier for users to add overriding snippets to
DOOMDIR/snippets.
+ Don't clear yas-minor-mode-map; the default keybinds can be useful,
esp to non-evil users.
+ Moved +snippets|enable-project-modes hook to autoloads file.
+ Reformat yasnippet config.
+ enable lexical-scope everywhere (lexical-binding = t): ~5-10% faster
startup; ~5-20% general boost
+ reduce consing, function calls & garbage collection by preferring
cl-loop & dolist over lambda closures (for mapc[ar], add-hook, and
various cl-lib filter/map/reduce functions) -- where possible
+ prefer functions with dedicated opcodes, like assq (see byte-defop's
in bytecomp.el for more)
+ prefer pcase & cond (faster) over cl-case
+ general refactor for code readability
+ ensure naming & style conventions are adhered to
+ appease byte-compiler by marking unused variables with underscore
+ defer minor mode activation to after-init, emacs-startup or
window-setup hooks; a customization opportunity for users + ensures
custom functionality won't interfere with startup.
