That means making keys, values, and items custom objects. Creating a new instance would have the overhead of creating 4 new objects instead of just 1. Is the added convenience worth it ? (Plus the extra layers of method calls for each access). I'm not sure. It's a nice idea in terms of using it (we could just leave the sequence attribute as an alias for the new keys attribute - for backwards compatibility).
