There is nothing to "fix" because NaN init is the right choice.

I work in float all the time (audio) and this "issue" is not even 
an issue, when I happen to have a NaN bug I'm actually glad I can 
track it down so easily thanks to its stickyness.

There are lot of things I'd want out of D floating point way 
before that:

- A way to warn for downcasts from double to float like -vtls. 
Domain-specific use but very much relevant.
- Making "fast math" options illegal, as they are enticing, vague 
and very dangerous.
- `real` could disappear, again this has been debated for days 
with no point. It doesn't hurt eigher to be here... just line NaN 
init.
