body: <p>Is there a more succint way to write the following code using option chaining and/or the elvis operator?</p>
  
  <pre><code>email.addSubject(if (creator != null)  String.format( inviteDescription, creator) else String.format(inviteDescriptionNoCreator, group))
  </code></pre>
  
  <p>It feels like there should be.</p>
