Yes, it is fixed (the link is to the history). -- Jason Dusek ___ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users

Oh, I just realized I had not changed the links, only the examples. They are all fixed now. -- Jason Dusek ___ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users

Standalone deriving allows you to get the convenience of deriving classes everywhere, not just on datatypes for which you can obtain, and use, the source.
