I'm in favour of having this __eq__ just return False. I don't think
the warning is necessary, and believe that people will complain about
getting it, but if that is the only way to achieve consensus,
so be it.

I believe we would have neither had we rich comparisons available
at the time. That unicode-vs-str-__eq__ raises an exception is just
a fall-out of not supporting __cmp__ (and it is good that __cmp__
is not supported - there is no meaningful way to order str/unicode
if the string is not in the system encoding).
