FWIW, see
http://wiki.python.org/moin/PythonDecoratorLibrary#head-b672f56dfbd9809e81572d719e230b2e9f053c0d

I think the library that links to
(http://www.phyast.pitt.edu/~micheles/python/decorator.zip) is does the nasty
stuff needed to correct the signature, probably using code similar to
http://mail.python.org/pipermail/python-dev/2005-May/053449.html

(Interestingly enough, the recipe before that on the wiki page is for a
'deprecated' decorator...)
