--- Comment #7 from Jonathan Wakely <redi at gcc dot gnu.org> ---
That is a reasonable design, but it is not the design used by the C++11
standard library. This is not the right place to debate the merits of a very
intentional decision made by a large group of experts after many months of
discussion. Please discuss it in a more suitable forum.
