   M.Delete (C2);
   pragma Assert (not Has_Element (C2));
   pragma Assert (not M.Contains ("two"));
--  double hash overhead.

   Replace_Element (C, -2);  -- dangling cursor

<< Does this behavior adequately satisfy your needs? >>

No, this checking is too overhead. And my need is not in the cursors
aria.

I would use the

   procedure Include
     (Container : in out Map;
      Key       : Key_Type;
      New_Item  : Element_Type);

in this cases. (this sample was based in AI302 without Include
routine.)
But I need some more routines without cursors. For example

   procedure Iterate
     (Container : Map;
      Process   : not null access procedure (Key : Key_Type; Element :
Element_Type; Stop : out Boolean));

analog of

   procedure Iterate
     (Container : Map;
      Process   : not null access procedure (Position : Cursor));

but without cursor.
And for every access routine with cursor there should be analog without
cursors IMHO.
