This is :
1. an additional step
2. an additional package
3. an additional level of inheritance.
That's why I was asking why it is not allowed to do this in one step as in
other OOP languages. Probably there exist some reasons for that.
Though GNAT provides efficient dispatching mechanism it is better to
minimize inheritance depth for derived types when possible.
Also creating additional packages just to provide visible fields for
private
tagged type is not handy.
Actually I was using additional packages but to my point of view this is not
very convenient.
