I just want to add, for completion, that discussion on #perl6 mentioned that there are different not-a-number values. Presumably NaN is only one of these, and it's possible through some computation paths to get other not-a-number values that aren't triple-equal to NaN. *Or* Perl 6 complete hides this difference and calls *all* not-a-number values NaN, so that NaN is actually a kind of representative for all not-a-number values, and if you want to be more specific than that, you have to create your own values and give them the appropriate behavior. Ticket is still resolved, but the above considerations may be of interest for someone who revisits this issue in the future.
