Just for the sake of completeness, I'd like to mention what setup.el
also provides.
The `:option' macro (which is comparable to `:custom' in use-package)
can take a complex option name. The default is something like
(:option c-default-style '((java-mode . "java")
(awk-mode . "awk")
(other . "k&r")))
but you could also use
(:option (prepend c-default-style) '(other . "k&r"))
to load the variable and then prepend a value to a list. In retrospect,
I don't like the syntax that much, and the fact that `:option' calls
`custom-load-symbol' unconditionally can really slow down a
configuration. This last thing is something that an `add-to-option` --
be it a standalone function or an extension of `add-to-list' must avoid IMO.
