I think what would happen if you were interoperating with ctypes is that you would get a datatype describing one element of the array, together with the shape information, and construct a ctypes array type from that. And going the other way, from a ctypes array type you would extract an element datatype and a shape.
Correct, assuming Travis' approach is accepted. However I understood that Martin was suggesting that ctypes types should be used to describe the structure of the buffer. Thus a buffer containing 10 integers would report its datatype as c_int*10.
I was probably mistaken and Martin was suggesting the same as you. In this case extended buffer protocol would still use a different model from ctype and "don't reinvent the wheel" argument goes away.
