I'm still working on fixing CPython's operand precedence bug for pure sequence types implemented in C [1], and, while trying to test bytearray, came across the problem that there doesn't appear to be a way to write a class in pure Python that redirects the PEP 3118 buffer access slots to another object (e.g. a memoryview instance or a bytes object).

Did I miss something? And, if not, would it make sense to have the buffer retrieval operations look for a __buffer__ method in the type dictionary as a last resort if the relevant C level slots aren't provided?

Would make sense indeed. Regards Antoine.
