title: Why would someone use the << operator in an enum declaration?
body: <p>I was looking at the code I have currently in my project and found something like this:</p>
  
  <pre><code>public enum MyEnum
  {
      open     = 1 &lt;&lt; 00,
      close    = 1 &lt;&lt; 01,
      Maybe    = 1 &lt;&lt; 02,
      ........
  }
  </code></pre>
  
  <p>The <code>&lt;&lt;</code> operand is the shift operand, which shifts the first operand left by the number bits specified in the second operand.</p>
  
  <p>But why would someone use this in an <code>enum</code> declaration?</p>
