At least _threading_local, cProfile, doctest, json, and perhaps future 
implementations of __sizeof__ for some classes would benefit from 
rewriting using IdentityDict. Unfortunately copy and pickle expose their 
replacements of IdentityDict to public and can't change them.

I don't known anything about general TransformDict use cases.
