Whenever I read a discussion about the dict, I always wonder whether the same thing applies to a set. Have you considered the utility of a TransformSet? Or is it YAGNI? Well, a TransformSet is like a normal dict, you just need to call the transformation function yourself when inserting the keys. s/normal dict/normal set/ No, read my example.

A TransformDict is like a normal dict, you just need to call the transformation function yourself when inserting the keys and insert a pair of (orig_key, value), or is like two normal dicts, you just need to call the transformation function yourself when inserting the keys and update parallel mapping from transformed keys to original keys.
