And it is already being used in the python-dev Summary!  I just sent the
rough draft to python-dev@python.org .  If anyone is curious to see the
notation in action the rough draft should be in the Maiilman archives
shortly.  Otherwise you can wait until I get the summary up and online
since I am planning on putting the original text versions up on python.org
along with the HTML version in hopes of getting more people into using
reST.
