[Haskell-cafe] Small Haddock question

This is irritating me now... Suppose I have something like the following: zero = 0 :: Int one = 1 :: Int two = 2 :: Int three = 3 :: Int How do I add Haddock comments to the end of each line? For some reason, Haddock doesn't like either of zero = 0 :: Int -- | Zero zero = 0 :: Int -- ^ Zero Either way it whinges about parse errors. How do I make it shut up and stop being so dense at me? :-} It's damned obvious what I want it to do...
