Well, I'm not going to argue with you. :-) I will point out a couple of
things that may affect you at some point:
- you can't use EOs as the key in a dictionary as the keys are copied so
your implementation won't work with EOs
- ordering the keys for the UI will be problematic, especially if the
ordering is not alphabetic.
