Sure--that's part of why we're treating Grammars as Classes that
(to some extent) can be compiled before use.  Though perhaps it's a
fundamental mistake to let the class choose the exact type over which
it operates, since that precludes generic code.

Well, that depends on how one defines "text", but by your definition,
I agree.  Though the danger of treating patterns as too powerful for just
text is that we run the risk of making patterns too powerful for text.
However lofty we aspire to get, we gotta keep our feet on the ground.
