<<(It also incorrectly passes the Stop parameter using in-mode,
>>

It was in "out" mode in my example

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

<< instead of
in-out mode, thus forcing the actual subprogram to set the Stop
parameter each time, if even you don't want to Stop.)>>

We could have one more Iterate procedure without Stop parameter in
Process procedure.

<<You can achieve the same effect using a cursor.>>

I understand that using of cursors allows to reduce the number of
routines in the Ada.Cursors. But i'm sure that using a much more
routines without cursors would reduce a potential errors at design
time. Using the *checking* cursors would move error detection into the
run time.
So, I know that i could build whatever i need on top of routines with a
cursors.
But I think that Ada standard should try to move design process into
the way where the errors would be avoided at the design time.
