are you 100% sure that this can be implemented on top of other RE
engines (CPython isn't the only Python implementation out there).

(generally speaking, trying to turn an RE engine into a parser is a lousy
idea.  the library would benefit more from a simple parser toolkit than
it benefits from more non-standard and highly specialized RE hacks...)
