[Python-Dev] Removing types module from stdlib

Should I start converting/removing uses of the types module where possible? So where we have: assert type(lineno) is types.IntType assert type(lineno) in (types.IntType, types.LongType) would become: assert type(lineno) is int assert type(lineno) in (int, long) or assert isinstance(lineno, int) assert isinstance(lineno, (int, long)) Preferences?
