title: Create a "clone" of this object, not point to it
body: <p>Let's say I got a list called</p>
  
  <pre><code>myFirstList
  </code></pre>
  
  <p>And then I want to create a copy of that list so I can do some tweaks of my own. So I do this:</p>
  
  <pre><code>mySecondList = myFirstList
  mySecondList.doTweaks
  </code></pre>
  
  <p>But I noticed that the tweaks also affect the <code>myFirstList</code> object! I only want the tweaks to affect the second one...</p>
  
  <p>And afterwards I will want to completely delete <code>mySecondList</code>, so I do <code>mySecondList = Nothing</code> and I'm good, right?</p>
