Or even better, just don't use list comprehensions, they're confusing:
let pairs = zip (randoms (-1,1) g0) (randoms (-1,1) g1)
Or even better, have a declaration instance (Random a, Random b) => Random (a, b) then do let pairs = randomRs ((-1, -1), (1, 1)) g0 Wouldn't it be nice if System.Random had an instance declaration for pairs?
