When I timed a simple pattern (abc.*def) on a 10000-character, Python
matches in ~7000 usec and Perl in ~8000 usec, but that proves nothing. I've
never seen a benchmark suite for regexes that made it possible to compare
two different regex implementations in any sensible way.

Huh?  Writing a sensible regex pattern that doesn't backtrack too much
requires the same set of skills no matter what the host language is.
