Another issue I can see with this approach is that it's not terribly obvious. Not that one should write nothing but pedestrian code -- if this is the right thing to do, then do it -- but I can easily imagine some poor maintenance programmer looking at this code and thinking "WTF? Why didn't he just use a HoH?"

Another point: specific operations will be O(1) instead of O(depth) if you know exactly where you want to go (i.e. you have a hash key already), but building the key may be O(depth), depending on how much information you have ahead of time. (And if speed's your concern, you can always snap the reference the first time you need it.)

In general, I'm not sure that this technique gives you much of a win, but I'm not clever enough to prove that it'll never be useful. :-) Nice job, and thanks for making me think.
