Or maybe something less radical:
generic
type Element_Type is private;
type Sort_Array_Type is array (Positive range<>) of Element_Type;
with function "<" (Left, Right: Element_Type) return Boolean is<>;
procedure Sort(A: in out Sort_Array_Type)
with Pre => A'Last < Positive'Last - 1;
I think this covers the problem expressed by the OP, right?
Pascal.
