Hi Chris I'm afriad I'd have to decline - generally in Haskell implicit "lifters" are problematic, so it isn't something I'd be looking to solve. There was a thread on Haskell Cafe about them last November called "Making monadic code more concise", that you might find interesting - especially Oleg Kiselyov's comments: http://www.haskell.org/pipermail/haskell-cafe/2010-November/086445.html Best wishes Stephen _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
