Why should that be true? What's wrong with treating it as an object
like anything else?
The trick is limiting the

undef is a property of the container variable (that it holds no value),
whereas NaN is a property of the content (like 1/0).

I'm thinking about how to explain Perl 6's numbers to the beginners
just picking up Learning Perl 6. I had some questions about NaN and Inf
(which I can't just try since neither Parrot or Pugs appear to know
about these yet).

There's a note about this in S02

Be mindful of the difference
