... while(nan) doesn't compile since nan isn't defined. Technically, it should be while(real.nan), but that was a bit unwieldy.
As for what it does, it turns out that despite nan comparing false to everything including itself, it's effectively the same as while(true). Go figure.

I would say there are two explanaitions that both sound halfway logical:
- Imagine the expression as being compared to true
or
- Read 0 as false and everything else as true.
