title: inheritance from win32com.client class in python
body: <p>I am using python2.7 with win32com module to access a win32 COM Library.
  with:</p>
  
  <pre><code>import win32com.client
  app = win32com.client.Dispatch('Word.Application')
  </code></pre>
  
  <p>I get an application object that works fine in python, although I do have only late binding
  available.</p>
  
  <p>Now I would like to inherite from this class:</p>
  
  <pre><code>class icad(app):
      pass
  </code></pre>
  
  <p>whicht throws the following exception:</p>
  
  <pre><code>TypeError: Error when calling the metaclass bases
  __init__() takes at most 2 arguments (4 given)
  </code></pre>
  
  <p>Is there a way to inherit from these COM classes at runtime?
  Metaclass seems to be the hint but I do not know where to start.</p>
