[Haskell] Haddock and type operators

[Wolfgang Jeltsch]

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
