   But with an overhead of opening files and unpickling. My wild guess
[not backed by numbers] is that it would be as slow.

   I suspect the only way to speedup things would be to precompile
regexps at compile (generating .pyc) time and saving compiled regexps in
the byte code file.

           Programmers don't die, they just GOSUB without RETURN.
