I am by no means an expert in this area, but isn't a "private package"
a solution here?
like :
package Parent is
type Base_Type is....
...
end Parent;
private package Parent.Child is
type Derived_type is new Base_type.....
...
end Parent.Child;
Or have i completly missed the point here? I thought this construct does
exactly this and "closes" any direct access to the child.
