OK... I meant something more radical (was actually discussed in another thread): getting rid of all pointers. I.e. (I borrow from the thread in question ;-) ):
        function find 
           (Set   : in Set_Type; 
            Index : in Set_Index) return Set_Index; 
GNAT is smart enough to select the pass-by-reference method.
In a similar experiment (a BZip2 decompressor) the pointer-free version was the fastest. Of course, no guarantee it will happen in your case... But it is worth a try.
