did you generate your code here with pyrex? If you want to jump in and rework our C extensions to be pyrex based and everything works out just as well or better than before, it'll be a great 0.9/1.0 feature. I've got a bit of experience with cython already as I've worked on lxml a bit, cython vs. pyrex any thoughts ? based on http://docs.cython.org/src/userguide/pyrex_differences.html they seem pretty similar (though cython seems more commonplace...)
