# Err. No it can't.
His point was that the NaN IEEE came up with is defined to have NaN !=
NaN, and that it might be confusing if Perl's behavior wasn't consistent
with that. Not that I think NaN != NaN is a particularly good idea, but
consistency with other languages may be. If NaN != NaN, then his
example is correct.
P.S. Congratulations to you and Larry for waking up perl6-language. I
had seen almost no traffic on it in weeks, and was starting to get a bit
worried that thoughts on the languages were coughing, sputtering and
dying. :^)
