Wow, interesting dialog there.

I'm in the camp that nan should be evaluated as false. I don't think I 
like the idea that !nan is also false, because this makes !!nan true!

TBH, I don't think I ever considered doing if(floatingpointvalue) to be 
a good idea in C or D. I generally stay away from float, and especially 
comparing to 0 directly.
