I find that hard to believe. re.compile caches its results, so except for
the very first time it is called, it is very fast -- basically a function
call and a dict lookup. I find it implausible that a micro-optimization
such as you describe could be responsible for speeding the code up by over
33%.

But since you don't demonstrate any actual working code, you could be
correct, or you could be timing it wrong. Without seeing your timing code,
my guess is that you are doing it wrong. Timing code is tricky, which is
why I always show my work. If I get it wrong, someone will hopefully tell
me. Otherwise, I might as well be making up the numbers.
