    Well, currently Squeampiler is in no way intended to obviate a lot
of the existing compilation mechanisms. If anything, it is intended to
complement them, though. :) However, making Squeampiler do some closure
optimizations would be cool, but would mean I'd have to make it more
knowledgeable of much higher level details (although I've been pondering
this lately for other things).
