title: Point-free style and using $
body: <p>How does one combine using <code>$</code> and point-free style?</p>
  
  <p>A clear example is the following utility function:</p>
  
  <pre><code>times :: Int -&gt; [a] -&gt; [a]
  times n xs = concat $ replicate n xs  
  </code></pre>
  
  <p>Just writing <code>concat $ replicate</code> produces an error, similarly you can't write <code>concat . replicate</code> either because <code>concat</code> expects a value and not a function.</p>
  
  <p>So how would you turn the above function into point-free style?</p>
