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
    [1 of 1] Compiling Main             ( Test.hs, Test.o )
    Linking Test ...
    /tmp $ haddock --version
    Haddock version 2.13.2, (c) Simon Marlow 2006
    Ported to use the GHC API by David Waern 2006-2008
    /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:
        GHC.Types.IO GHC.Integer.Type.Integer
    /tmp $

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.
