[Python-checkins] commit of r41348 - peps/trunk

[brett.cannon@python.org]

Author: brett.cannon
Date: Sat Oct 29 05:22:31 2005
New Revision: 41348

Modified:
   peps/trunk/pep-0352.txt
Log:
Update the code for BaseException to have 'args' be more backwards-compatible.
Also reformat some methods to use the conditional operator to make the code
simpler.

Also moved the deprecation of 'args' and '__getitem__' to Python 2.9 so that it
won't be removed during the 2.x series.
