I hate going off track, but:
######################################
class CounterExample:
def __eq__(self, other):
return True
print "is?", CounterExample() is None
print "==", CounterExample() == None
######################################
That being said, this is an evil and perverse example.
In any case, setting something to None might not be such a bad thing.
'del someVariable', on the other hand, is almost always a bad code
smell. It's much too low level; it's evidence that the code is not
taking advantage of simple mechanisms like functions or local
variables.
