    The canonical example of such a storage container is
    ``defaultdict(set)``. Thus, the return value of this method contains

    Args:
        config (dict): Defines the configurations for the storage.
            For in-memory storage, the config ``{'type': 'dict'}`` will

            contain references to environment variables, in which case
            literal configuration values should be replaced by dicts of
            the form::

        name (bytes, optional): A reference name for this storage container.
            For dict-type containers, this is ignored. For Redis containers,
