@sweetyBaby, it's not tail-recursive because the last thing the function does (in the recursive cases) is invoke the ::: operator. Thus, the recursive call to sumList is not in tail position. As I mentioned, I think you should use a higher-level abstraction rather than using recursion directly in this particular situation. But if you'd like to learn more about tail-recursion see oldfashionedsoftware.com/2008/09/27/…
