I see why you'd do the split, but my preference is to keep it as 
ext/numeric_traits and __numeric_traits instead of the name change.

Since these are compile time, keeping it named traits is IMHO clearer 
than moving it to something that suggests std::numeric_limits.
Of course, it doesn't help that std::char_traits is not a compile time 
trait... thoughts?
