Each adjunction gives rise to one monad; it's the reverse direction (factoring a monad as an adjunction from which the monad arises) for which Kleisli and Eilenberg-Moore are the extremal choices. (Not that this bears on the point you were making.) _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
