Correct. The re module keeps a cache of the last N regexes used, for some

But if you have an application that makes heavy-duty use of regexes, e.g.
some sort of parser with dozens of distinct regexes, you might not want to
rely on the cache.
import re
re._MAXCACHE
512
Have you ever seen a program that uses 512 re's?
I havent :-)
I do not know if the cache was always there. It used to be smaller,
maybe 100, then 200.
