Aren't the warnings just about as usefull as failures? Anyway, you could always use the -Werrror flag for ghc... In any case, I would not like to have to implement an entire typeclass at once... it would interfere with incremental development. -- Sam _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
