title: How to remove the first 50 items in a list without copying it?
body: <p>I have a very large list, and I'd like to iteratively remove the first 50 elements without copying it (as for example something like <code>list[50:]</code>).</p>
  <p>My initial thought was by doing:</p>
  <pre><code>[list.pop(0) for i in range(50)]
  </code></pre>
  <p>What would be the most performant way to do this?</p>
