- ido will actually be loaded at startup - I'm hoping there's a better
way to optimize this.
- ido-sort-mtime-mode was fixed
- Up/Down were added to get closer to
`(setq ido-vertical-define-keys 'C-n-C-p-up-down-left-right)`
- Faces were re-enabled
- The number of results are now displayed with ido
+ 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.
