[Python-Dev] Regexp 2.7

[Jared Grubb]

Would there be any interest in augmenting the test case library for  
the regex stuff?

When I was working on PyPy, we were using a simplified regular  
expression matcher to implement the tokenizer for Python. I was able  
to take a lot of PCRE's regex tests and port them to test our regular  
expression implementation (to make sure the DFA's were being optimized  
properly, etc).

I believe the PCRE test library was under a very liberal license, and  
so we may be able to do the same here. If there's interest in it, I  
can do the same for Python.
