A frozen "any iterable" is not necessarily a tuple.
For example, a frozen binary tree should probably keep the tree
structure and methods; a frozen dict.keys() should be a frozen set; and
its not clear what a frozen iterator should do. Should it run the
iterator to exhaustion? Seems odd.
What about non-collections? What's a frozen re.MatchObject?
