Do anyone know of a set container class for Cocoa objects, that use
pointer semantics.

Like this:
        NSMutableString  * s1 = [@"Hello" mutableCopy],  * s2 = [@"Hello"
mutableCopy];

        Somesetclass *someSet = [[Somesetclass alloc]init];
        [someSet add:s1];
        [someSet add: s2];
// After these calls, someSet should contain 2 elements because s1 !=
s2 by pointer semantics

Depending on your exact needs, maybe NSCountedSet would be useful.

I have decided to do an implementation myself, as an objective c++ wrapper to std::set<id>. I want to use the class to aid in destruction of directed cyclical object graphs,
in dual mode frameworks. NSHashTable
