I have no problem with namespace nesting, but please do not try to do
namespace composition with using-directives. On a conforming compiler, they
do not work as expected. In particular, template name lookup will not
proceed through a using-directive. Individual using-declarations must be
used instead, as we did for boost/cast.hpp

(CodeWarrior is the only compiler I know of which is conforming in this
regard. Most others will let you get away with the using-declaration)
