No, that's not sufficient. Pyrex treats special
methods (__add__ etc.) very differently in extension
types. In a Python class, they're just ordinary
Python methods. In an extension class, they're
C functions that are plugged directly into the
relevant slots of the type object, and they
have different signatures.

And before you ask, no, we couldn't use 'cdef __add__',
because that already means something else (it
defines a C method, which is like a virtual method
in C++).
