There still is getClassIndex(), but it is more complicated and possibly
slower: you need to get index of sphere first, remember it somewhere
etc. typeid is standard operator, which accepts type or object.
Therefore you can test if(typeid(*b->shape)==typeid(Sphere)); the
disadvantage is that (unlike dynamic_cast), it will be false for Shapes
derived from Sphere, which is not so much concern, I think;
getClassIndex() would fail there, too.
