I did not suggest a change.  I wrote: "I am not suggesting any
language changes, but I think it will be
useful to explain why float('nan') != float('nan') somewhere in the
docs."  If there is a concise explanation for the choice of IEEE 754
vs. Java, I think we should write it down and put an end to this
debate.
