    33GHC includes a new (in 2010) mechanism to let you write generic functions.  It is described in [http://www.dreixel.net/research/pdf/gdmh_nocolor.pdf A generic deriving mechanism for Haskell], by Magalhães, Dijkstra, Jeuring and Löh.  This page sketches the specifics of the implementation; we assume you have read the paper.

    5 This mechanism replaces the [http://www.haskell.org/ghc/docs/6.12.2/html/users_guide/generic-classes.html previous generic classes implementation]. The code is in a branch of GHC; you can get it with `darcs get http://darcs.haskell.org/ghc-generic-15Feb11/ghc`. 
     5This mechanism replaces the [http://www.haskell.org/ghc/docs/6.12.2/html/users_guide/generic-classes.html previous generic classes implementation]. The code is in the `ghc-generics` branch of the GHC, base, ghc-prim, and testsuite repos.
