My fingers were ahead of my thought. What I mean was that Base_Class
is class wide type while Base_Type and Derived_Type are not. That
means there should be case 3 for it.
Cloned : Base_Access := new Base_Class' (Base_Class (Orig)); -- case
3
By the way, I made another error while typing the word Therefore. But
it turned out to be Thefore.
