Is there any chance this can be treated as a bug and fixed for the
release of 2.1? Alternatively, given that we're already breaking code
with the change in the way complex numbers are handled, should cmp() now
raise an exception *every* time the type/class differs?
I think the current situation is going to cause major problems trying to
explain Python, particularly on the Unicode side.
