Cannot place -- ^ comment after GADT constructor

[nr]

This might be the same problem as ticket #43; I couldn't quite tell. The offending code is

{-# LANGUAGE GADTs #-}
module Haddock
where

data Lit a where
  I :: Int  -> Lit Int  -- ^ an integer
  B :: Bool -> Lit Bool -- ^ a Boolean

And Haddock reports

Haddock.hs:6:24: parse error on input `-- ^ an integer'

[nr]

Just the code shown in the ticket -- makes Haddock fail with a parse error
