My point is to be able to see that result generated was X and that it did not match expected Y, where both X and Y are printed out. -- http://wagerlabs.com/ ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Why can't you just do 'f 1 2 3 == (4, 5, 6, 7)' to test f?
