Python is a giant cache-miss generator. A little performance boost
on the opt-code dispatch isn't going to change that much. If we
really do care about improving python to do less environmental
damage, then that is a discussion we should be having on it's own
merits. It was really out of place, even in this tangenty thread.<br>

<p dir="ltr">I'm a qualified engineer (in computer systems
engineering), so caring about environmental sustainability is
part of my professional ethical standards, not just a matter of

<p dir="ltr">Given the power draw of large data centres, the
environmental impact of performance improvements to the Python 2
series is a point well worth considering.</p>
