Changing `dict` keys during iteration will now be detected in certain corner cases where the number of keys isn't changed (but they keys themselves are), and a `RuntimeError` will be raised.
Changing ``dict`` keys during iteration of the dict itself, ``keys()``,
``values()``, or ``items()`` will now be detected in certain corner cases where
keys are deleted/added so that the number of keys isn't changed.
A `RuntimeError` will be raised after ``len(dict)`` iterations.
