Please don't. Python 3 was so painful because we decided to make millions of tiny backward incompatible changes. To have a smooth Python 4.0 release, we should only remove things which were already deprecated since at least 2 cycles, and well documented as deprecated. I'm being flippant here because of the triviality of the change. Anyone using PyVACOPY or PyMEMCPY can fix their code in a backwards and forwards compatible manner in 7 seconds with a sed command.

In fact, this kind of thing would be perfect for Python 4.0 - it's technically backward incompatible (thus justifying the 4.0 number), but removes only things that have been deprecated for some time, and have simple and direct translations.
