Actually, that's not 100% accurate. The C code calls the same functions. Most 
of the extra cruft is that it needs to do all of this error checking and type-
dispatch, while in C++ you can have RAII and templates.

At least last time I read up on it, cython was not able to do multi-type code, 
i.e., have code that works on arrays of multiple types. Does it support it 
now?
