How is the end user supposed to actually use nullptr if it's not global? It's a keyword in C++11; boost::nullptr is not legal.
namespace X { BOOST_USING_NULLPTR; void foo() { int * p = nullptr; } } // namespace X is the basic usage I had proposed. BOOST_USING_NULLPTR expands to some empty statement in C++11 and "using ::boost::nullptr" in C++03. - Jeff
