&gt;the above question is for curiosity sake, it doesn&#x27;t change the point that CPython is where new language features are added.<p>So far. Everything changes the moment the PyPy team announces they&#x27;re an official continuation of Python2. They can easily integrate more 3rd party backported features from 3-&gt;2 into PyPy4. Guido doesn&#x27;t really matter there.<p>That said, it doesn&#x27;t take that to get me to use PyPy. The speed improvement is a dream come true. Writing pure Python is much more preferable to me than writing a C extension thus PyPy is the present and future for most of us.
