Vladimir,
Your examples seem to indicate that you've misunderstood the change
that's proposed for Python 3000. Especially this:

Python 3000 will not do anything like this. It'll try a.__cmp__(b),
and failing that b.__cmp__(a) (but imagine this using tp_ slots
instead of actual Python method calls), and if both return
NotImplemented, it'll throw a TypeError (rather than guess, which is
what it does now).
There's a lot of legacy oddness in PyObject_RichCompare() and its many
helper functions; presumably they'll delete some of that, but it won't
be anything you care about.
Comparison with None should also continue to work as it does now,
unless I missed something.
