Are you sure? I don't see any special handling of sequences in its docs or code...

The one in unittest doesn't have this feature. However there's assertApproxEqual defined locally in the test/test_statistics.py package that does. Since the other is only meant for local use in test_statistics.py, we should leave it alone. The one in unittest is pretty bad but widely used; deprecating it won't have any teeth.
