Doesn't numeric_cast already do want you want for narrow_cast<> ?

I would agree with the idea for unsigned_cast though, for template code it
is often necessary to convert some charT to its unsigned equivalent (for
array lookup), currently I've used the traits technique to handle this
(since I had a traits class anyway), but some well defined cast would be as
good.
