Yes, Ring is the most basic class in the hierarchy that provides a zero, a one and addition, thus you could implement fromInteger by successively adding or subtracting one from zero, given some basic operations on Integer. 'fromInteger' just allows a more efficient implementation. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
