title: Elixir: How to test multiple values in case condition?
body: <p>Is there a shorter way to write this:</p>
  
  <pre><code>case testvalue do
    200 -&gt;
      true
    404 -&gt;
      true
    _ -&gt;
      false
  end
  </code></pre>
  
  <p>It returns true for 200 or 404 and false for everything else. It would be nice to write it with an OR condition but this leads to an error:</p>
  
  <pre><code>case testvalue do
    200 || 400 -&gt;
      true
    _ -&gt;
      false
  end
  </code></pre>
