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.
