PEP-505 isn't anywhere close to being finished. I only submitted the draft because somebody off list asked me to send a draft so I could get a PEP number assigned. So I literally sent him what I had open in my text editor, which was just a few minutes of brain dumping and had several mistakes (grammatical and technical).
If there's absolutely no point in continuing to work on it, I'll drop it. But from the outset, I thought the plan was to present this in its best light (and similar to the ternary operator PEP, offer several alternatives) if for no other reason than to have a good record of the reasoning for rejecting it.
I'm sorry if I misunderstood the PEP process; I would have kept it to myself longer if I knew the first submission was going to be reviewed critically. I thought this e-mail chain was more of an open discussion on the general idea, not specifically a referendum on the PEP itself.
