Are you sure ? what about the following example ?
Is this also shadowing ?

Python 2.5 (r25:51908, Sep 19 2006, 09:52:17) [MSC v.1310 32 bit
(Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import __builtin__
>>> __builtin__.True = False
>>> __builtin__.True
False
>>> True
False
