title: Example of an Fmap to distinguish from map?
body: <p>My understanding is that the difference between map and fmap is that the latter can return a function?</p>
  
  <p>I'm studying the functors section of this <a href="http://learnyouahaskell.com" rel="noreferrer">http://learnyouahaskell.com</a> and some of the explanation is a bit unclear.</p>
  
  <p>Map and fmap behave identically in the following:</p>
  
  <pre><code>let exMap = map (+1) [1..5]
  let exFMap = fmap (+1) [1..5]
  </code></pre>
  
  <p>What is a good example of an fmap returning a function? </p>
