Good idea, but won't work retroactively out of the box. So you'd need a
helper script to figure out your current state (using portage version
and tree snapshot maybe), then prepare the environment to upgrade
(and how do you handle the "common" case of python 2.5 only which
doesn't allow newest portage anyway?)
