Well, the objects need to be stored somewhere. If we don't want to deal with
reallocation, we need a container
whose iterators are stable under insert, for example a list or a set.

You are now able to use the iterator to that container to access the
objects.

std::vector <someIterator> v;
v[123]->functionCall();
or
v.front()-> dataMember;
or
(*v.begin())-> dataMember;

Would that help?
