Also worth noting too, is this example from J.P. Rosen, in a paper  =

explaining the OO Model of Ada 2005.

    with Ada.Text_IO; use Ada.Text_IO;
    with Calendar;
    package Persistance is
       type Services is interface;
       procedure Read
         (F : in File_Type;
          Item : out Services) is abstract;
       procedure Write
         (F : in File_Type;
          Item : in Services) is abstract;
       procedure Set_Expiration
         (To_Date : in Calendar.Time) is null;
    end Persistance;

Note how he Used Ada.Text_IO and just Withed Ada.Calendar.
