[TIP] mock.ANY not actually ANY?

I have a mock that is using assert_called_with() and mock.ANY thus:

m = mock.Mock()
m.assert_called_with(now=mock.ANY, foo='bar')

Unfortunately, this results in:

AssertionError: Expected call: mock(now=<ANY>, foo='bar')
Actual call: mock(now=datetime.datetime(2012, 1, 9, 22, 36, 41, 264838),

I could have sworn that ANY used to work perfectly fine when used in this
way. Is this a datetime thing or...?
