Hi,

I'm having difficulties with this function I wrote:

iterateR :: (MonadRandom m) => (a -> m a) -> a -> m [a] iterateR g s = do s' <- g s return (s:) `ap` iterateR g s'

As a side note, the MonadRandom constraint is funny, since this function doesn't depend on any sort of randomness. You may consider changing the constraint to simply Monad m => ... -Brent
