Suppose you have
type Root is abstract tagged ...
procedure Very_General(X : in out Root);
private
procedure Internal_Updating(X : in out Root'class);
and then Root has a son and a daughter
type Son is new Root with ...
and
type Daughter is new Root with ...
and suppose that Son and Daughter need to use Root's Internal_Updating
procedure. If they are both declared in the same package as Root, no
problem. Even if they are declared in child packages of Root, no
problem. But if they are declared in truly separate packages, then
either they cannot see Internal_Updating, or else you move
Internal_Updating to the public part of Root's package, thus letting
anybody see and call Internal_Updating.
How would you propose structuring this if you are required to have
1-1 package/class?
