Didn't Fredrik Lundh strongly imply that implicitly compiled objects are cached? That's a pretty big speed up right there.

Sure, the precompiled objects are faster because you don't have to find them. But you could have string objects (or a derivative) grow a "compiled_regexp" attribute internally. Then if you have a random regexp you think you might have used elsewhere, just intern it. (NB, wild guess, here, I don't know enough about current implementation to know if this is a reasonable extension.)

+1. I won't have time for some weeks, but I'd already flagged Barry's post for later consideration. I hope that doesn't stop somebody else from picking up the ball, though.
