I'd just like to add my support for keyword arguments. Functions like
write-region are both horrible and brittle because their parameters are
both numerous and overloaded; specific functionality can be more simply
expressed with using keyword arguments. Precedent can be seen in
play-sound, defcustom, and elsewhere. The performance arguments opposing
keyword arguments don't seem to be supported by benchmarks, and in any
case, most functions, especially ones with rich functionality, aren't on
the fast path.
