If you are including arrayobject.h, then intp is exactly Py_intptr_t.  
Since intp is what is used internally in numpy, why not use it in a 
numpy wrapper.

So, basically, I'm not sure what your point is.

I can see the case for the __array_struct__ interface which does not 
have to include arrayobject.h, then you need to use Py_intptr_t.
