Functions defined in Pyrex are C-implemented functions,
which don't trigger the method binding magic when you
access them through a class. The same thing happens if
you try to use a built-in function as a method.

What *should* work is to define the method inside a
class in Pyrex (plain class, not extension type) and
extract it out of the class's __dict__. That's because
Pyrex pre-wraps a function defined in a class in an
unbound method object before putting it in the class.

I have suggested that builtin functions should be
given the same method-binding behaviour as interpreted
functions. The idea wasn't rejected out of hand, but
I don't think anything has been done about it yet.
