__contains__ operation in ItemsView, ValuesView and Sequence in collections.abc simply test equality with ==. This introduces inconsistent behaviour with built-in containers when encountering objects like NaN, which does not equal to itself. I asked something about this on core-mentorship, see https://mail.python.org/mailman/private/core-mentorship/2016-April/003543.html.
