Discussion:
This was originally editorial PR #5789 which is considered not-editorial.
std::flat_set and std::flat_multiset
have operator<=>
so <compare> should be included in the corresponding header,
in the spirit of LWG 3330.
#include <compare> is also missing in the adopted paper
P1222R4.
[2022-09-23; Reflector poll]
Set status to Tentatively Ready after eight votes in favour during reflector poll.
[2022-11-12 Approved at November 2022 meeting in Kona. Status changed: Voting → WP.]
Proposed resolution:
This wording is relative to N4917.
Modify the synopsis in 23.6.10 [flat.set.syn] as indicated:
#include <compare> // see 17.11.1 [compare.syn] #include <initializer_list> // see 17.10.2 [initializer.list.syn]
