        # This test creates a complex arrangement of frozensets and
        # compares the pretty-printed repr against a string hard-coded in
        # the test.  The hard-coded repr depends on the sort order of
        # frozensets.
        #
        # However, as the docs point out: "Since sets only define
        # partial ordering (subset relationships), the output of the
        # list.sort() method is undefined for lists of sets."
        #
        # In a nutshell, the test assumes frozenset({0}) will always
        # sort before frozenset({1}), but:
        #
        # >>> frozenset({0}) < frozenset({1})
        # False
        # >>> frozenset({1}) < frozenset({0})
        # False
        #

        # implementation-dependent.  Small changes to Python's sort
        # algorithm cause the test to fail when it should pass.
