  Would it even make sense?  I though a large part of the intent was
to for performance, avoiding memory copies.  Perhaps there should be
an .__as_buffer__() which returned an object that supports the C
buffer interface.  I'm not sure how useful it would be; perhaps for
classes that represent image data?  They could return a buffer object
created from a string/array/NumPy array.
