I have been working my way through "Learn You a Haskell for Greater Good" and am stumped when I get to the "Syntax in Functions - Pattern Matching" section.
The book shows the following expression...
ghci> lucky :: (Integral a) => a -> String
As far as I can see, the live version of `the section you mention`_ on learnyouahaskell.com does not contain this text - it doesn't have the "ghci> " at the beginning of the line. Besides what others have said in response to your question, I would add that you should make sure to read LYAH on the website if possible - other sources might be out of date, as I think the author does update the website version from time to time. .. _the section you mention: http://learnyouahaskell.com/syntax-in-functions#pattern-matching -Keshav
