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.
