-Takes, in order:
-  1. Optional properties :local and/or :append, which will make the hook
-     buffer-local or append to the list of hooks (respectively),
-  2. The hooks: either an unquoted major mode, an unquoted list of major-modes,
-     a quoted hook variable or a quoted list of hook variables. If unquoted, the
-     hooks will be resolved by appending -hook to each symbol.
-  3. A function, list of functions, or body forms to be wrapped in a lambda.

-    (doom-modeline-add-hook! 'some-mode-hook 'enable-something)
