Duplicate elements are *not* ignored when comparing *actual* and
*expected*. It verifies if each element has the same count in both
sequences. Equivalent to:
- ``assertEqual(Counter(iter(actual)), Counter(iter(expected)))``
+ ``assertEqual(Counter(list(actual)), Counter(list(expected)))``
but works with sequences of unhashable objects as well.
