Alas, the same problem is at the root of both:  the regex interface wasn't
thread-safe.  Introducing a separate "match object" makes re thread-safe, but
the extra object also means more teensy steps are required to get a really
simple task done.  regex is wholly deprecated (lack of thread safety was a bad
design error); re partly makes up for it by offering many more regular
expression features.
