Hello, On pdf page 43 of YAHT it provides a code example. I typed this into a file named "Guess.hs" and tried unsuccessfully to load it into ghci. I am running ghci version 6.8.2 This is the output it gave me: " [1 of 1] Compiling Main ( Guess.hs, interpreted ) Guess.hs:19:12: parse error on input `doGuessing' Failed, modules loaded: none. " I've attached the code module. As far as I can tell it is identical to the example in YAHT. Did I type it wrong, is the tutorial wrong, or something else? thanks again, Jared Langson
