Internally, three different things may be done for storage:
- Simple keys can utilize the Dictionary class, we just use one of those
inside the map.
- If the key implements Hashable, we can hash it.
- Otherwise, use mx.utils.ObjectUtil to generate a hash for any other key and
also to compare the keys. Keys are then wrapped in a KeyWrapper object
that implements Hashable. This last case will also handle null as a key.
