Generating NaNs should be quite trivial. I can do it like this:

   #debug str(1/0 - 1/0, 0, 3)

It shows up as "nan", not as "#QNAN" here on Mac OS X, but I guess 
that's an implementation detail of my C library.

(For some reason POV-Ray here considers 0/0 as inf, while I'd expect it 
to be nan - and in my own programs, it is.)
