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/haskell/config.el -- lexical-binding: t; --`

:boom: Change first arg of load! macro load!'s first argument is no longer a symbol (that will cause void-variable errors now) to save on unnecessary interning and simplify compile-time logic. It accepts any valid form that evaluates to a string now. If you use load!, you need to change its argument to a string! e.g. (load! +my-module) => (load! "+my-module") 2018-05-27 12:44:22 +02:00			`(cond ((featurep! +intero) (load! "+intero"))`
