My response to this is simply "yuck". This is a hack, abd I
don't think it's worthwhile. If you want to test for None, test
for None. Similarly, if you want a dictionary lookup to default
to a no-op method, there's a perfectly simple way to spell it now:

    def defaultNoopMethod(*args, **kwargs): pass
    somedict.get(key, defaultNoopMethod)

You can even do this as a one-liner using a lambda if you want.
