Not only name-clashes, but also overloads, I think (a positive side-effect
is less potential for confusion). Implementors (naturally) enjoy the luxury
of living in namespace std, applications don't (§17.4.3.1). Thus,
::std-extensions from implementors imply not defined behavior, whereas for
the rest of us, they're undefined behavior. :-)

So I agree with Anthony; they'd better live in ::boost.
