Should we promote args[0] to a named argument here, because we depend on
it having a specific type? It's not truly as polymorphic as we're making
it appear.

That type here is iotests.QMPTestCase because we're relying on case_skip
being present.

def test_wrapper(test_case, *args, **kwargs):
    ...
        return func(test_case, *args, **kwargs)
