That's not /entirely/ true; in Ada 2012:
-----------------------
-- ADS_Example.ads --
-----------------------
pragma Ada_2012;
Package ADS_Example is
-- The stupid old reverse-a-string beginner's exercise.
Function Reverse_String( Input : String ) return string;
private
Function Reverse_String( Input : String ) return string is
(case Input'Length is
when 0 | 1 => Input,
when others => Input(Input'Last) &
Reverse_String(
Input(Input'First..Positive'Pred(Input'Last)) )
);
End ADS_Example;
---------------
-- Main.ads --
---------------
with
Ada.Text_IO,
ADS_Example;
Procedure Main is
Text : constant String:= "This is a test.";
begin
Ada.Text_IO.Put_Line( "Starting." );
Ada.Text_IO.Put_Line( "Text: " & Text );
Ada.Text_IO.Put_Line( "Reversed: " & ADS_Example.Reverse_String(Text) );
Ada.Text_IO.Put_Line( "Finished." );
end Main;
