HI Stefan, thank you very much for responding my e-mail to cython's list.

About the proposal, I'd be very happy in helping the cython community doing
the task 'rewrite modules in CPython's standard library in Cython that are
currently written in C'. I didn't think about any special modules, but I'm
going to start doing it, in my opinion, both modules you've mentioned are
really good examples.

I think this project could be very important, but, I don't know CPython very
well, are there any examples you could suggest me to understand CPython
better? I think I could do a good effort to understand this as fast as I can
and we discuss more the proposal.

Waiting for your reply...

Best Regards..
