Steven, this appeal to things unmentionable is not an acceptable way to
oppose a PEP. In the text you quoted I didn't see Chris claim consensus --
just that he has written up his version. It's ready for review because he
wants feedback -- "ready for review" is *not* code for "this is the final
word from the community, now the BDFL must speak."

Your posts make me worried that we have turned into a political body rather
than a group of technical enthusiasts trying to improve the language they
all love.

I don't think you can reasonably disagree that a PEP is needed -- not with
so much discussion and apparently still no agreement.

If you oppose the specific proposal, say what you think is wrong with it.
If you think it needs more input from other experts, name those experts. If
you think it needs more input from a community, name that community.

I haven't actually read the PEP, so I don't have an opinion about it (my
post last night was just an attempt to reword something quoted in the email

I just saw Antoine's response, and at least he talks about the proposal,
not the politics around it. But he's awfully vague. We need a concrete
counterproposal. Possibly a competing PEP. Anything but references to
things that happened off-stage. If you have a personal beef with Chris,
this is not the place.
