Yes. This is also why you should *carefully* rethink the requirement
for having this operation in the whole hierarchy. It should not come
up by default.
Also, you will want to use boost::shared_ptr or something similar to
protect yourself from the pointer mess. Raw pointers are to be
avoided, even if pointer-related patterns have to be used.
