Here's a draft (please provide me with whatever you can remember, I've been
following the list on gmane and my history's therefore lost):

PEP: XXX

Abstract
========

This PEP tries to list all BDFL pronouncements on Python 3000 that
refer to changes that will not happen and new features that will not
be introduced, sorted by topics, along with a short explanation or a
reference to the relevant thread on the python-3000 mailing list.


Core language
=============

* Python will not have programmable syntax.

   Thread: "It's a statement! It's a function! It's BOTH!"
   http://mail.python.org/pipermail/python-3000/2006-April/000286.html

* There won't be a syntax for ``zip()``-style parallel iteration.

   Thread: "Parallel iteration syntax",
   http://mail.python.org/pipermail/python-3000/2006-March/000210.html


Standard types
==============

* Iterating over a dictionary will yield the keys.

   Thread: "Iterating over a dict",
   http://mail.python.org/pipermail/python-3000/2006-April/000283.html


Coding style
============

* The maximum line width will be 80 characters.

   Thread: "C style guide",
