This is most a list for announcements; beginners at haskell.org is better for
these kinds of questions, and haskell-cafe at haskell.org for general

pred :: Int -> Int

n+k patterns were part of Haskell '98, but removed from Haskell 2010. You
may be able to use the pragma

    {-# LANGUAGE NPlusKPatterns #-}

to turn them back on.
