Then why do you write, let me quote:

"""
(snip) coding __eq__ (snip) buys you
nothing from the != operator. != isn't (by default) a synonym for the
negation of == (unlike in, say, every other language ever); not only
will Python let you make them mean different things, without
documenting this fact - it actively encourages you to do so.

I was not commenting on the actual design choice, just stating that it 
is actually documented.

And you're talking about strawman ??? Come on, you obviously can tell 
the difference between a one-line statement and your above strawman 
argument, don't you ?

Please understand that I'm not arguing about this particular design 
choice (and FWIW, I'd mostly agree on the point that having a != b 
different from not (a == b) is actually a wart). I'm just correcting 
your statement about the behaviour of __eq__ / __ne__ not being 
documented, which is obviously false.
