It would seem to me that the Right Thing is for the closure to return
something to ~~ against.  However, this obviously means that the regex
engine is going to have a harder time optimizing, and be somewhat more
complex, since it has to keep calling out to the smartmatcher.

Possibly we should make the syntax be a smart match, but only require that
conformat implementations implement ranges and integers.
