I object, strongly. This is a feature addition, and has no business going
in post-rc1, especially with no time for review.

As far as the function case goes, I'm not really thrilled about layering
more functionality on that until we've come to some understanding about
how to select from a group of overloaded functions. It may be that this
is orthogonal to that issue ... or maybe not. I don't have any objection
to fixing the non-function cases, as long as it's only in HEAD.
