title: How to denote return type tuple in Google-style Pydoc for Pycharm?
body: <p>In Pycharm I want to have a documented function that returns a tuple so that I can get code completion on it. The style of comments is Google-style.</p>
  
  <hr>
  
  <p>This <strong>works</strong> correctly:</p>
  
  <pre><code>def func():
      """
  
      Returns:
          str: something
  
      """
      pass
  </code></pre>
  
  <p>Typing <code>func().</code> correctly shows methods for <code>str</code>.</p>
  
  <hr>
  
  <p>However, typing this <strong>does not</strong> work anymore:</p>
  
  <pre><code>def func():
      """
  
      Returns:
          (int, str): something
  
      """
      pass
  
  a, b = func()
  </code></pre>
  
  <p>Typing <code>b.</code> does not offer anything.</p>
  
  <hr>
  
  <p>I know that PyCharm is capable of parsing tuples, because this code <strong>works</strong>:</p>
  
  <pre><code>def func():
      """
  
      :rtype: (int, str)
      """
      pass
  
  a, b = func()
  </code></pre>
  
  <p>However, this is not according to the Google style.</p>
  
  <hr>
  
  <p>How do I document a function according to the standard so that Pycharm will pick up on the return types?</p>
