Off the top of my head I think using & and | within character classes
will cause confusion.

        / (<~(X & Y) | Z> | <Q & R>) & <M | N> /

So much for the "visual pill" of <xxx>

Also, character classes don't currently utilize parentheses for
anything. This is a good thing as you don't have to distinguish between
which parens are within assertions and which are without. Or do you
proposed that even the parens within assertions should capture to $0
and friends?
