Please read my posts about the Python type-object verses normal Python 
Object situation.  That really is the crux of the matter.

Ctypes uses a Python type object for every data-format.
NumPy uses an instance of a data-type object for every data-format.

What advantage do we gain by making every instance of a data-type object 
*also* a Python type object?  We get a lot of head-ache.  Have you seen 
what ctypes had to do?  It had to define a new Dictionary object so it 
could attach it to the tp_dict parameter because you can't just inherit 
from the PyTypeObject and add the fields you want to the structure.    
This is my argument.

I for one am not going to put any effort in that direction.  People are 
free to do it, if they want, of course.  But, it's no small change.   I 
would, however, put effort into "undertstanding ctypes objects" as 
data-type objects.
