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


Builtins
========

* ``hash()`` won't become an attribute since attributes should be cheap
  to compute, which isn't necessarily the case for a hash.

   Thread: "hash as attribute/property",
   http://mail.python.org/pipermail/python-3000/2006-April/000362.html


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

* Iterating over a dictionary will continue to yield the keys.

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


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

* The (recommended) maximum line width will remain 80 characters,
  for both C and Python code.

   Thread: "C style guide",
   http://mail.python.org/pipermail/python-3000/2006-March/000131.html
