Looks like I'm still missing a couple functions ;-) BTW, Is it true that
strings in python are immutable?

Fair enough -- it's the reason I've try to explain my position in terms of
code whenever possible.

I thought the c++ was pretty readable. As for free functions, I'm not
opposed, but so far I haven't seen a proposal that makes the code clearer to
my eye.

I wasn't trying to suggest that Python didn't support regex. I mostly leave
Python I still haven't written any significant programs in it. One day...

How does that phrase'll be a cold summer day in Az (a balmy 105 now)
before we 'all' agree ;-)
