Whether the fix above is adopted, at least one container > implementation in libstdc++ is not conforming. > Correction: if the additional requirement is adopted, there will be no need to modify libstdc++ code for conformance. The inconsistency will remain literally (`_Node_alloc_traits::_S_nothrow_move()` in the std::list vs. implicit `_Alloc_traits::_S_nothrow_move() ...` implied by _Rb_tree), though.
