Not so good question, because the answer is obvious. :-)
But I'm not sure if the two questions are as connected as they might
seem to. I use a shared_ptr to express object ownership; and we all
know that it's rarely wise to express ownership of a Derived object
through a (shared) pointer to Base if the Base destructor isn't virtual.
I don't think that my question has been answered yet.
