Just asking what seems like the obvious question. The regexp engine is intertwined with at least half a dozen perl ops. It might be possible to write a pluggable regexp engine that accepts code references conforming to this sort of API, but a: I don't know how easy it is b: I changed the regexp API somewhat with the move to first class regexps, and left that job only part done, because I didn't update the pluggable API.
