On the other hand, the PEP doesn't do much to address the various claims of readability issues. Whether they are subjective or not, well-founded or not, the PEP does (in my view) come across as unnecessarily dismissive of the question of readability. I suspect that's largely due to Chris being extremely tired of having the same arguments over and over again, and I can understand that. However, I think it could be covered more completely - the remainder of your post is exactly the sort of response that would be useful to have recorded. But one way or another, I think people will vote on the PEP based on their (subjective) views, and so readability will get factored into the overall response, one way or another. To what extent that response affects Guido's final decision (I can't see him delegating on this one!) remains to be seen, and honestly, I'm willing to trust Guido's intuition.
