Right, so provide a better identityHash implementation in the image (e.g.: implement hash and then have identityHash call hash instead), and problem solved...

If lookups find the sought object in mostly one attempt, the primitive is overkill... most of the time, the real issue is the quality of the hash function.
That's true, but this is not the case with the 4096 hash values.

i think that #pointsTo: is a cheat :), which you can use in Sets but not dictionaries, because it contains associations. Also, it works only for identity-based collections.
Dictionaries don't have to use associations (for example MethodDictionary doesn't use them), that's why #pointsTo: works (MethodDictionary also uses it).
I wonder how LargeIdentityDictionary compares to your dictionaries'.
me too.
If you give me a pointer to the source code, I can run the benchmarks.
