Could you elaborate a bit? What are the pros and cons of writing an 
extension module using the Cython API compared to using the CPyothon 
API? In particular, how portable is it? Can I compile a module in one 
and use it in the other? Don't I just tie myself to a different API, but 
tie myself nonetheless?

Thank you!
