It's hard to imagine arrow notation without arr (or at least contravariance in the first argument of the "arrow") because forming expressions using the local environment is so central to it. That is, I can't imagine what things you are trying to write in that situation. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
