I think that if you require a commutative operator, the order doesn't matter (except for efficiency and possible rounding issues, I guess). -k -- If I haven't seen further, it is by standing in the footprints of giants _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
