And you don't need to be called Simon to use it, but you surely need to be careful with it's use if you want to write safe code (you won't need it in most case, only in very specific situations and in writing some new strange libraries). -- Jedaï _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
