Of the ideas I've seen in this thread, only two look reasonable:
* Do nothing. This is attractive because it doesn't break anything.
* Have float.__eq__(x, y) return True whenever x and y are
the same NaN object. This is attractive because it is a
minimal change that provides a little protection for
simple containers.
I support either of those options.
What's the flaw in using isnan()?
There are implicit comparisons being done inside list.__contains__() and other
such methods. They do not, and should not, know about isnan().
