Subject: [PATCH 4/9] Use "is" not "==" for None
Using == is not always a good idea when dealing with None's, for example, if you have this class:
`class NotNone: __eq__ = lambda self, other: True`
Then NotNone()==None returns True
But NonNone() is None returns False
And PEP 8 says: "Comparisons to singletons like None should always be done with 'is' or 'is not', NEVER the equality operators."
