BREAKING CHANGE: Racer is no longer developed and its project page
recommends using rust-analyzer instead. Moreover, users have reported
issues trying to build/install it on recent versions of rust, so I've
removed support for Racer from Doom, and now default solely to LSP for
IDE features.
Users that want these features will need to activate the module's +lsp
flag (along with the :tools lsp module) and install rust-analyzer. See
the module's README for instructions.

+ 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.
