NaN does not have to be a float or a Decimal. Perhaps it should have its own class. Perhaps, but that wouldn't solve anything on its own. If this new class compares reflexively, then it still violates IEE754. Conversely, existing NaNs could be made to compare reflexively without making them a new class.

And 3rd party NaNs can still do whatever the heck they want :)

Cheers, Nick.
