Not really.
1. Unbounded_String is a compromise needed when the string length change
during its life. The great majority of cases allocate [and initialize] a
string just once. [addressed to be the cases when using a discriminant
does not work]
2. There is nothing for arrays that are not strings and for other
indefinite types. E.g.:
type Node_Type is record
Item : new Element_Type'Class;
Prev : Node_Ptr_Type;
Next : Node_Ptr_Type;
end record;
3. There is nothing for serialization and marshaling objects logically
containing strings and other indefinite types.
