title: Python getting IDE linter to see from System imports within pythonnet's clr
body: <p>I am using the <code>pythonnet</code> package in MSMQ communications.  In my IDE (PyCharm CE), I have the following sample code:</p>
  
  <pre class="lang-py prettyprint-override"><code>#!/usr/bin/env python3 
  
  import pythoncom 
  import clr
  
    clr.AddReference("System") 
  clr.AddReference("System.Messaging") 
  from System import TimeSpan
   from System.Messaging import MessageQueue 
  </code></pre>
  
  <p>Aside: this code works fine when I actually run it using Python <code>3.6</code>.</p>
  
  <p>And below is a screenshot of what it looks like inside PyCharm.</p>

  <ul>
  <li>For <code>System</code> it says: <code>Unresolved reference 'System'</code></li>
  </ul>
  
  <p>Other than using <code>noqa</code> comments, <strong>how can I get my PyCharm linting to do the following</strong>:</p>
  
  <ul>
  <li>Not complain about <code>from System import XYZ</code>?</li>
  </ul>
