[Haskell-cafe] an example from YAHT doesn't run

[trifod at gmail.com]

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
