Major optimization refactor, across the board + 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. 2017-06-08 11:47:56 +02:00			`;;; lang/rust/config.el -- lexical-binding: t; --`
