Are you referring to the arrows package at <http://hackage.haskell.org/package/arrows>? If so, what do you mean by "systematic lifting", because it does lift operations through the transformers where possible. -- Dave Menendez <d...@zednenem.com> <http://www.eyrie.org/~zednenem/> _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
