title: import all future features
body: <p>Just curious, I tried <code>from __future__ import *</code>, but I received this error:</p>
  
  <pre class="lang-none prettyprint-override"><code>  File "&lt;stdin&gt;", line 1
  SyntaxError: future feature * is not defined
  </code></pre>
  
  <p>Well, that makes sense.  A <code>__future__</code> import is a little special and doesn't follow the normal rules, but it got me to thinking: how <em>can</em> I import all the future features?</p>
