[issue31580] Defer compiling regular expressions

New submission from Barry A. Warsaw: It's a very common pattern to see the following at module scope: cre_a = re.compile('some pattern') cre_b = re.compile('other pattern') and so on. This can cost you at start up time because all those regular expressions are compiled at import time, even if
