I currently know about these two issues related to fixing the docs:
http://bugs.python.org/11945 - about NaN values in containers
http://bugs.python.org/12067 - comparisons
I am working on the latter, currently. The patch only targets the
comparisons chapter in the Language Reference, there is another
comparisons chapter in the Library Reference, and one in the Tutorial.
I will need to update the patch to issue 12067 as a result of this
