--- Comment #11 from Jonathan Wakely <redi at gcc dot gnu.org> 2011-09-14 15:26:23 UTC --- And for std::regex, what would be more useful than just "it's not fully implemented yet" would be listing what's missing, e.g. I disabled support for anchors because it was buggy, see PR 49870 (which you'll notice noone has closed as INVALID or WONTFIX)
