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.

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 personal preference:

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.
Cheers,
Nick.
