[Haskell] Haddock and type operators

Hello everybody, I urgently need Haddock support for type operators like in the following code snippet: infix 2 :::, := infixl 9 :.: data name ::: value = name := value newtype Composition f g a = Composition { runComposition :: f (g a) } type (:.:) = Composition Does anybody know whether this is easy to implement or whether there is a quick hack to make this work? Can I do the hacking myself or is deeper knowledge of the Haddock source code necessary to provide this feature? Thank you in advance for any help. Best wishes, Wolfgang
