Glad to offer real help rather than just stupid comments for once =)

Mostly having to do with handling strings that fall outside of the
narrow spec you provided.  As Andrew noted, passing a string such as
"a.1" would be a problem as "." has meaning in the re module.  You
should add some validation code to make sure that anything passed to the
constructor (in the sequence argument) is valid.  However, if you *know*
the strings will always be properly constructed, there shouldn't be a
problem.
