Surely it's possible to inherit even from C 'classes'?  I remember seeing
something about this in, I think it was the SWIG manual, when I scanned
through it.

I wonder if it's possible to get gmp to work with NumPy on the C level, ie
not using arrays of Python objects, but as an array directly accessible
from C libraries using gmp?  I've never used gmp, or NumPy's C API, so I
have no idea.
