no, it's not -- None is keyword, and just like any other keyword, it can't
be re-bound. However, every other keyword I tried to rebind results in a

(except None, True, and False)

which I suppose is because while None is a keyword, it can be used pretty
much anywhere any other name can be used (as opposed to say, def)
