This is about some minor changes to the bytes, bytearray, and memoryview classes. Here is the PEP: https://www.python.org/dev/peps/pep-0467/
I am waiting for this to be merged, or approved, or whatever is the next step. Someone on the bug tracker mentioned restarting the discussion on the mailing list, so that is what I'm trying to do here. Does anyone have any thoughts?
