This matcher compares the evaluated object to the negation of the given
    matcher. If the ``match`` argument is not a matcher, it is implicitly
    wrapped in an :py:func:`~hamcrest.core.core.isequal.equal_to` matcher to
    check for equality, and thus matches for inequality.

Examples::

assert_that(cheese, is_not(equal_to(smelly)))
