"""Wraps a matcher to define equality in terms of satisfying the matcher.
``match_equality`` allows Hamcrest matchers to be used in libraries that
are not Hamcrest-aware. They might use the equality operator::
assert match_equality(matcher) == object
Or they might provide a method that uses equality for its test::
library.method_that_tests_eq(match_equality(matcher))
One concrete example is integrating with the ``assert_called_with`` methods
in Michael Foord's `mock <http://www.voidspace.org.uk/python/mock/>`_
library.
