Programming is a big world.

For the things I do, nan works well. I've had to point out many 
times here and elsewhere that 0 is a great default if you're 
going to calculate a sum. If you're taking a product, it's an 
absolute disaster, and it's hard to detect unless you end up with 
something like a division by zero. At least nan doesn't work its 
way through the system silently, and it's easy to test for 
errors, unlike the case of 0.

If nan is a problem, then `double x;` shouldn't compile. Setting 
x to 0 is no better for correctness than setting it to a random 
number. Either way, you're pretending the compiler knows what it 
should be, and that's impossible.
