--- Comment #7 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-11-08 08:11:58 UTC --- Just a note to the accidental reader: C++11 as published is well known to miss quite a number of constexpr. Adding those is conforming, a specific DR covers that. In any case, the primary isn't really the issue here, I suppose, assuming there is an issue whatsoever (not for me ;)
