The pattern object contains a reference to the original pattern
string, so I guess the answer is "yes, but indirectly".  But the core
engine doesn't really care -- it just follows the instructions in the
compiled pattern.

That's what I originally proposed (and implemented).  But this may
(in theory, at least) break existing code.  If not else, it broke the
test suite ;-)
