[Haskell-cafe] Random this! ;-)

1. Implement a function rollNDiceIO :: Int -> IO [Int] that,
given an integer, returns a list with that number of pseudo-
random integers between 1 and 6.
After a lot of learning what not to do, this is the best I could come up with.
rollNDiceIO :: Int -> IO [Int]
rollNDiceIO n = mapM (\x -> randomRIO(1,6)) (replicate n 1)
I know, ugly, but at least I got it to work. What's a better way to generate this list?
