In the same vein, I noticed two days ago that type trait boost::conditional is present when including "boost/type_traits/conditional.hpp" (but not defined by boost/type_traits.hpp) and thus
std::tr1::conditional is not defined when including "boost/tr1/type_traits.hpp"
After some searching, it turns out that 'conditional' was not part of TR1 (that explains the above) but that it was added with N2240 to the C++ 2011 standard: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2240.html
Hence my question, should 'conditional' (and probably 'enable_if') be added to "boost/tr1/type_traits.hpp" ?
