[Haskell-cafe] Haddock docs don't list instances

Web versions of Haddock documentation, even this old one, list a class's instances. http://www.haskell.org/ghc/docs/6.2.2/html/libraries/base/Prelude.html#5 My Haddock documentation does not have any class instances at all. This is true both of the documentation that comes with my Linux system (I use Debian) and of the documentation I generate locally using cabal-install or the Setup.hs program in my homemade packages. How do I get Haddock to make the instance lists? Anybody else have this problem--maybe it is a Debian bug? Thanks. --Omari -- Pay a little now, or pay a lot later.
