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.
