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).
