I wouldn't dispute that. I have no experience with Jython/IronPython
to confirm what they do. Also, this ordering for None is unmentioned
in PEP 207:

http://www.python.org/dev/peps/pep-0207

Nor is it tested in test_richcmp.py. That said, in CPython the
ordering hasn't changed since rich comparisons were added in 2.1a
(circa 2001):

http://hg.python.org/cpython/file/b60831eeab5a/Objects/object.c#l514

Without this exception, comparing to None would use the type name
(currently "NoneType", but "None" in v2.1), which I realize is also
unspecified in the docs.
