- SPC o r now prompts for a REPL to open when none was found for the
current buffer.
- REPL handlers must now follow the naming convention "*/open*-repl".
e.g. +python/open-ipython-repl, +emacs-lisp/open-repl, etc.
- +eval/open-repl has been split in two:
- +eval/open-repl-other-window
- +eval/open-repl-same-window
subword-mode is enabled by default for no other language, nor is it the
default behavior in vim (and it affects evil word motions), so it should
be opt-in.

Conform to conventions, use `add-hook!` for multiple hooks, use single semi-colon for eol comments, remove comments redundant with code, and use sharp-quote to indicate function symbol.
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")
Now that we are loading package autoloads files (as part of the
generated doom-package-autoload-file when running make autoloads), many
:commands properties are redundant. In fact, many def-package! blocks
are redundant.
In some cases, we can do without a config.el file entirely, and can move
into the autoloads file or rely entirely on package autoloads.
Also, many settings have been moved in their module's autoloads files,
which makes them available ASAP; their use no longer depends on module
load order.
This gained me a modest ~10% boost in startup speed.
package-initialize, once again, isn't called on every startup, which
means package autoloads won't be loaded in most interactive sessions, so
must do it manually for certain packages.
The warning confusingly states that `ghc-mode` couldn't be found, implying it's some kind of emacs mode. However, the predicate is actually checking for the `ghc-mod` executable, which is something entirely different.
+ 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.
