Exactly. And that's the very reason to make an immutable copy it MUST
send the objects -copy, storing whatever they return.
If the objects inside happen to be immutable, they just return
themselves, and it's all right.
If the objects inside happen to be mutable, they returns their copies,
and it's all right again.
It's called object-oriented. You (in this case the array) don't know
and don't NEED TO know what the objects actually are. You just sent
them appropriate message, and they take appropriate action.
Alas in this case the message is not sent, and thus the action is not
taken :(((
