title: Are sets ordered like dicts in python3.6
body: <p>Due to changes in <code>dict</code> implementation in Python 3.6 it is now ordered by default. Do <code>set</code>s preserve order as well now?</p>
  
  <p>I could not find any information about it but as both of those data structures are very similar in the way they work under the hood I thought it might be the case.</p>
  
  <p>I know there is no promise for <code>dict</code>s to be ordered in all cases but they are most of the time. As stated in Python docs:</p>
  
  <blockquote>
    <p>The order-preserving aspect of this new implementation is considered an implementation detail and should not be relied upon</p>
