As a followup question: would it be considered a compatibility-breaking
change to rename PyTypeObject names? As a concrete example, in
Modules/_elementtree.c the name of Element_Type (essentially the
xml.etree.ElementTree.Element replacement in C) is "Element". For the
purpose of pickling/unpickling it should be named "_elementtree.Element" or
"xml.etree.ElementTree.Element" or some such thing. Can such a change be
made between 3.3 and 3.4? Between 3.3 and 3.3.1?
