[Python-ideas] PEP for issue2292, "Missing *-unpacking generalizations"

The PEP is attached. I'm not sure if I've covered the basics, but it's a try. If anyone knows how to get the patch (from the bug report) working, or where to find http://code.python.org/python/users/twouters/starunpack after code.python.org was deleted in favour of hg.python.org (which seems not to have it), it'd be nice to know.
