No, you didn't understand the code I posted which explicitely demonstrated 
the same point you repeated.  Again:

>>> globals()['None'] = 'ha'
>>> None
>>> dir()
['None', '__builtins__', '__doc__', '__name__', '__package__']
>>> globals()['None']

The point of the the last two lines is that the assignment *was* made but 
was ignored in line 2 [because, obviously, the interpreter bypasses the 
normal lookup procedure].
