Yes, it should be a very tiny help.. except if config.hpp also uses pragma once ;-)

You don't think it's, maybe, relying on implementation details of config, and, maybe, that's not a good thing?

Maybe ;-) It's not something new in boost: http://www.boost.org/doc/libs/1_57_0/boost/type_traits/config.hpp #ifndef BOOST_CONFIG_HPP #include #endif Nothing will break if boost/config.hpp does not define BOOST_CONFIG_HPP, we'll just loose the tiny help. It's ugly, I agree, but I don't think this is a problem for anyone. Ion
