This was a bit unexpected as memoryviews support all the methods of the Sequence abstract base class: >>> import collections >>> b = bytearray(b'asdf') >>> isinstance(b, collections.Sequence) True >>> m = memoryview(b) >>> isinstance(m, collections.Sequence) False It would be nice if memoryview was registered with the Sequence ABC and MutableSequence for writeable memoryviews.

There's no ducktyping for this due to the Sequence/Mapping confusion so it's a simple missing explicit registration.
