square :: (Num a, Num b) => (a ,b) square (x , y) = (x*x , y*y)
How can I specify that the square functions output would be a pair ?
Why don't you try it without the type declaration, and see what Hugs or GHCi thinks the type is? This should make it pretty clear what the problem is, I think. -kzm -- If I haven't seen further, it is by standing in the footprints of giants
