Well basically, you want an object that's a Map for all intents and
purposes, but does a couple of things differently. So e.g. you need a
custom set and all Map operations that use set need to use that new
set. Tab's original message explains that however as far as I can tell
so it's not entirely clear to me what we're missing.
