The challenge with that is "global" (i.e. across-interpreter) objects.
There are several of these: the obvious singletons (None, True, False),
the non-obvious singletons ((), -2..100 or so), and the extension module
globals (types, and in particular exceptions).

Do you want them still to be global, or per-interpreter?
