I have decided to do an implementation myself, as an objective c++

"Dual mode" as in both Retain-Release and Garbage Collection? If
so, be
careful. I don't think an std::set will keep strong references to the
Obj-C objects it contains. You may need to CFRetain()/CFRelease()
your
objects manually.

No It won't; However, I intend to use this class only from the
dealloc method of the object that manages
the object graph, so that it will be possible to reclaim the space if
the framework is run on systems without gc
enabled.
What I intend to do is :
1 Create a custom subclass of NSCoder, that stores each object pointer
passed to encodeObject:
in a set.
2. Retains each set member
3. Passes each set member a message telling it to release each
reference it's retained.
4. Release each set member
and 5. Release any references kept directly in the managing object.
