Yes, I already override items(), keys(), values(), their iter... 
versions, and just about every damn method that dicts have :/

I suspect that the dict() constructor is just grabbing the key/value 
pairs directly from the underlying hash table. If that's the case, my 
choices are to not inherit from dict at all, or take your suggestion and 
keep an auxiliary dict alongside the main one.
