[MLton] Int Overflow detection

[Neophytos Michael]

That's fine but when I interact with the standard lib I give and receive ints
and not words so I have to "decorate" my code with Word.fromInt and
Word32.toIntX which is not very nice or convinient.

For example instead of writting:
------------------------------
fun sum a =
  let
    val l =  (Array.length a)
    fun loop (i, res) =
        if i = l then res
        else loop (i + 1, Array.sub (a, i) + res)
  in
    loop (0, 0.0)
  end
------------------------------

I have to write:
------------------------------
fun sum a =
  let
    val l = Word32.fromInt (Array.length a)
    fun loop (i : Word32.word, res) =
        if i = l then res
        else loop (i + 0w1, Array.sub (a, Word32.toIntX i) + res)
  in
    loop (0w0 : Word32.word, 0.0)
  end
------------------------------
