title: What is Kotlin equivalent for bitwise or with assignment '|='?
body: <p>How to write in Kotlin:</p>
  
  <pre><code>flags |= newFlag
  </code></pre>
  
  <p>Only what I have found is:</p>
  
  <pre><code>flags = flags or newFlag
  </code></pre>
  
  <p>Is there a build-in <code>bitwise or</code> operator with assignment?</p>
