title: Sphinx doc struggling with import typing
body: <p>today, I setup a simple sphinx job for my python project. When I hit "make html" it crashes with the following messages:</p>
  
  <blockquote>
    <p>WARNING: autodoc: failed to import module 'myname.mymodule'; the following exception was raised:
    cannot import name 'MyClass'</p>
  </blockquote>
  
  <p>I deleted line by line and now, if I remove </p>
  
  <pre><code>from typing import Tuple
  </code></pre>
  
  <p>in front of myname.mymodule, sphinx does the docu with errors (can't find Tuple) of course.</p>
  
  <p>I can easily attach the log, referenced by sphinx, but the only intresting in it is this:</p>
  
  <blockquote>
    <p>while not self.fetch_token().match([OP, '='], NEWLINE, COMMENT):
    AttributeError: 'NoneType' object has no attribute 'match'</p>
  </blockquote>
  
  <p>Does sphinx has a problem with typing? Or is there something broken with my imports ?</p>
