title: from file import variable creates copies of variables
body: <p>If I </p>
  
  <pre><code>from file import variable
  </code></pre>
  
  <p>and the <code>varable</code> is changed in module file, the <code>variable</code>s value is not updated.
  If I</p>
  
  <pre><code>import file
  </code></pre>
  
  <p>the varaible <code>file.variable</code> is updated.</p>
  
  <p>Is there a way of selectively importing variables from a module, placing them in the modules local scope and having the updates reflected.</p>
