Re: Feature proposal: unittest.mock.NAN

    NaNs are special in that math.nan != math.nan, so you can't just do
assert_called_with(math.nan).

class ProductionClass:

...     def method(self):
...         self.something( math.nan )
...     def something( self, x ):
...         pass
...

real = ProductionClass()
real.something = MagicMock()
real.method()
real.something.assert_called_once_with( math.nan )
