Here is the most relevant part (quoting Guido):

Okay, but does that count as a pronouncement that should go across all
versions and platforms?
I believe there are differences between when __eq__ and __ne__ are
called between Python 2 and 3, and I don't see any docs on the expected
behaviour for python 2, dunno about 3.
I'm willing to write these docs,
http://docs.python.org/reference/datamodel.html#object.__eq__ feels like
the right place, is there anywhere else they should go or be linked to from?
Mark Dickinson gave some useful insights into this, and Milko Krachounov
provided these useful comparisons on #python:
Python 2

Python 3

Do they cover it all or has anything been missed?
cheers,
Chris
