That's the whole point. We want to inherit from Ellipse (non-abstract)
some of its methods, but we do not want to inherit the representation
(two doubles). Of course, if you change the representation, you lose
view conversions and thus an ability to pass Circle by-reference where
an Ellipse is required. You have to pass it by-copy instead. C++
cannot this, it lacks in out parameters, but Ada well can.
