New submission from Raymond Hettinger <rhettin...@users.sourceforge.net>:
class T(unittest.TestCase):
def test_items_equal(self):
# this test fails, but should succeed
a = [{2,4}, {1,2}]
b = a[::-1]
self.assertItemsEqual(a, b)
This method has a fast-path using sorted() and a slow-path that doesn't care
about cross-type comparisons. The fast-path is incorrect though and gets the
wrong answer in the above test case.
