I just realized that it would be impossible to use weak_ptr with any hash. The problem is that the hash function would have to use weak_ptr's get() method. Then if the underlying object of the weak_ptr gets destroyed, get() will suddenly return 0 instead of the previous pointer, so the hash function will now map the weak_ptr to a new bucket. Is there any way to add a member function that returns a const void * that will be invariant even if the underlying object of the weak_ptr has been destroyed?
