Some patches for GHC/base are attached to http://hackage.haskell.org/trac/ghc/ticket/4834. They're a couple of years old, so they may not apply cleanly, but they might help you in assessing the impact of such a change. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
