Actually the compiler warns you that 'None' is s special name that you
probably _didn't_ want to rebind.  But you have.  As you can see, the
compiler doesn't issue such warnings with regard to 'True' and
'False.'  Does that explain it?

>>>def spam(): pass
...
>>>None = spam()
<stdin>:1: SyntaxWarning: assignment to None
>>>False = bool(spam())
>>>True = bool(spam)
>>>(None, False, True)
(None, False, True)
