Brett, your trigger finger is a tiny bit itchy. I believe this is a
followup on the earlier thread about denial-of-service against hashing
functions, where Uncle Timmy pointed out that regexes are far more
troublesome. Scott's more likely to get good testcases out of c.l.py,
IMO, but this is certainly an appropriate place for discussion if he's
planning to roll code back into the system.

This is Python. We don't care much about theory, except where it intersects
with useful practice. --Aahz
