title: Check if int is between two numbers
body: <p>Why can't do you this if you try to find out whether an int is between to numbers:</p>
  
  <pre><code>if(10 &lt; x &lt; 20)
  </code></pre>
  
  <p>Instead of it, you'll have to do</p>
  
  <pre><code>if(10&lt;x &amp;&amp; x&lt;20)
  </code></pre>
  
  <p>which seems like a bit of overhead.</p>
