Speak for yourself. There are a fair number of people on this thread whose
employer pays them to work on Python. And this thread originated when a
patch was being contributed by people who were also paid by their employer
to do all the dirty work (including benchmarks). And yet they were
(initially) given the cold shoulder by some "high and mighty" Python 3
zealots. This attitude need to change.

Please let someone else do the explaining. I don't want to have to do the
damage control after you "explain" something.
