You might be able to get away without a PEP, but you'll definitely
need to post an implementation patch to the bug tracker
(http://sourceforge.net/tracker/?group_id=5470&atid=105470).  Once
you've posted your implementation, you should send an email to
python-dev asking folks what they think about it.  Be sure to give
some code examples that using this decorator would simplify.
