Explanation: If both tests fail, return the 'id' (identity) function which when applied to (show n) will return the number as a string. If one or both tests succeed, return a 'const' function which will simply return the appropriate string and ignore the (show n). This example was illuminating. It helped me realize I'm wasting too much time with Haskell.
