I didn't imagine it could be longer than 1 second overhead - and if
you have so many regexps, it must do something so nontrivial that 1
second doesn't matter. Perhaps I have a different mindset about this
:-).

What's so ugly about it? The fact that you need to rewrite the cache
when you change some of the regexps? I can't imagine you change more
than, say, 10 of the regexps a day (compiling of which is an
insignificant performance hit) and when you "ship" the script, you
will freeze the regexps anyway.
