- The existing module used undecidable instances, a Haskell extension which is supported by GHC but not by Hugs.
??
as far as i recall, Hugs was the first Haskell implementation to bite the bullet and accept undecidable instances as a design option (although its predecessor apparently also had the undecidability feature). http://cvs.haskell.org/Hugs/pages/users_guide/class-extensions.html are you thinking of interactions with other extensions, perhaps? claus _______________________________________________ Hugs-Users mailing list Hugs-Users@haskell.org http://www.haskell.org/mailman/listinfo/hugs-users
