package P is
   type T is new Root_Stream_Type with private;
   procedure Op (O : not null access T);  -- or whatever
private
   type Control_Type (O : not null access T) is
     new Limited_Controlled with null record;

   -- override Init and Final as req'd

   type T is new Root_Stream_Type with record
      Control : Control_Type (T'Access);
      -- other components as req'd
   end record;
end P;
