IdentityDictionary is the name of a Smalltalk class that uses identity instead of equality when comparing keys: http://minnow.cc.gatech.edu/squeak/1845 In Python, it would allow arbitrary objects as keys, and allow equal duplicates as different keys. For pickle, this would mean that we could save both the creation of the id() object (since the object itself is used as a key), and the creation of the tuple (since the value is only the position).
