================
Comment at: include/type_traits:595
-template<class _B0, class _B1>
-struct __and_<_B0, _B1> : conditional<_B0::value, _B1, _B0>::type {};

----------------
It is not impossible that this was a compile-time optimization for the (probably very common) case where there's only 2 arguments. I'd like to have Marshall's input on that, since he seems to have written that code. Otherwise, LGTM. Ping @mclow.lists
