True, but it would probably make more sense to find a way to let Pyrex 
re-use the method descriptor already used for builtin types:

 >>> type(str.lower)
<type 'method_descriptor'>

Interestly, I just discovered that method descriptors for builtins don't 
define im_class, im_self or im_func. I never knew that - I thought they 
had the same interface as instance methods.

Cheers,
Nick.
