------- Comment #5 from paolo dot carlini at oracle dot com 2010-03-27 20:00 ------- Evidently, you never studied the actual specs: the C++1x traits are different, in many *incompatible* ways, eg is_lvalue_reference / is_rvalue_reference vs is_reference. Many C++1x traits don't even compile in C++98 mode. And about the various introspection traits which you mentioned, changing those now would break *a lot* of applications which assumed for *many* years essentially PODness for yes, as the TR1 specs allowed. No way.
