Yeah, as a regular Cython user I'm not sure if I really understand Chris'
Cython uses precisely that C-API to create the extension modules it makes. If
you've ever used the same C-API manually you'll understand why Cython exists
to make it easier.
Also, Cython *only* works with the standard interpreter (the latest release
claims alpha quality support for PyPy but I haven't tested that myself).
