In the future, please try with more recent version of GHC.
This is no longer a parse error with HEAD or 7.6.3.
Uhm, actually there is, with 7.6.3.
% cat haddock.hs

It's great that it's fixed in HEAD.

Strange.

    /tmp $ ghc --version
    The Glorious Glasgow Haskell Compilation System, version 7.6.3
    /tmp $ cat Test.hs
    module Main (main, y, x) where

    -- | this is a main 123 function
    main :: IO ()
    main = return ()

    -- | Haddock likes 'y' and 'x', 'foobar'
    (x, y) = (1, 2)
    /tmp $ ghc Test.hs

    /tmp $ haddock --version

    /tmp $ haddock Test.hs --html
    Haddock coverage:
    Warning: Couldn't find .haddock for export Main.y
      50% (  2 /  4) in 'Main'
    Warning: Main: could not find link destinations for:

Well, it's a high possibility that my Haddock version isn't the stock
one that comes with 7.6.3. In any case, I'm glad that you say it's
fixed in HEAD. Thanks for checking.
