I don't think anyone posited it as a replacement for the middle one? We
could replace Char->Bool with Text->Bool, but it would be slower (and yes,
that matters to me). I don't intend to add it myself, but you're welcome to
put together a patch and a set of QuickCheck tests.

Because you can't do a Boyer-Moore search off it.
