You are absolutely correct, it should not have gone to python-dev. It
was supposed to go to python-3000, where the initial discussion took
place, where Guido asked for someone to write the PEP right off the
bat. However, as much as I love GMail, it makes it less than easy to
always know which mailing list I'm on, so I actually thought I was in
that discussion at dev, not 3000. I apologize to everyone for mixing
the threads between lists! This is exactly why I need to start pulling
in all the dev lists to the summaries.
