Surely you haven't forgotten your own recipe?
    http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/163968
That was also published in the Python Cookbook (2nd Edition) as recipe 
19.4: "Unpacking a Few Items in a Multiple Assignment".

As mentioned in the recipe, the original discussion was here:
    http://mail.python.org/pipermail/python-dev/2002-November/030380.html
The last message posted on the thread was from GvR, who was against it:
