This is Mark Russell's patch:

[ 1009560 ] Fix @decorator evaluation order

From the description:

Changes in this patch:

- Change Grammar/Grammar to require
newlines between adjacent decorators.

- Fix order of evaluation of decorators
in the C (compile.c) and python
(Lib/compiler/pycodegen.py) compilers

- Add better order of evaluation check
to test_decorators.py (test_eval_order)

- Update the decorator documentation in
the reference manual (improve description
of evaluation order and update syntax
description)

and the comment:

Used Brett's evaluation order (see
http://mail.python.org/pipermail/python-dev/2004-August/047835.html)

(I'm checking this in for Anthony who was having problems getting SF to
talk to him)
