I've never really seen a satisfactory visual scheme for clearly representing higher order functions
I saw a visual scheme for this purpose at FDPE'08. It uses an alternating colouring scheme, representing arguments as holes: a hole in a black thing is white and a hole in a white thing is black.
I only found an ACM link: http://portal.acm.org/citation.cfm?id=1411272 Cheers, Sebastian _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
