--- Comment #1 from Jiang An <de34 at live dot cn> ---
There's (or will be) a new DR CWG2749 which tentatively ready now.
https://cplusplus.github.io/CWG/issues/2749.html
It seems that the old resolution in CWG2526 was wrong, and the comparison
should be constexpr-friendly.
BTW I don't think there was anything specifying that "the comparison would have
*undefined* behaviour" before CWG2526.
