Subject: [PATCH] Add Queue `show` method to hide backing Deque

I was looking over the Queue method per #479 and while I didn't find any issues I noticed that during printing at the REPL the backing Deque is printed inside. Decided to try to write a small show method to hide the backing type to pretty it up.
