I think the suggestion Joe has made about division is good,
but I also think it is overkill!
Let's not add even more things to the Prelude that are not
going to be used. My opinions on this matter is:
- have something which is efficiently implementable
(i.e. close to what the hardware provides) as the
primitive, which is what `div` is.
- just add an extra function for what Kent wants, e.g.
infix 7 `quo`
x `quo` y = if x < 0 then x `div` y - 1 elsse x `div` y
or whatever is approproate.
