It seems like you should be able to get instances for: (Monoid m) => Monoid (RVarT n m) (Num m) => Num (RVarT n m)
and so forth for integral and floating Just wondering if I am missing something here or if there is any particular thing I'm missing. I am aware you would probably not be able to do an Eq or Show instance but me understanding was that in the case of the (Num b) => Num (a -> b) instance the solution was simply to leave those things undefined. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
