From: "de34 at live dot cn" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug libstdc++/111327] std::bind_front (and std::not_fn) doesn't always perfectly forward according to value category of the call wrapper object Date: Thu, 28 Sep 2023 08:36:18 +0000 [thread overview] Message-ID: <bug-111327-4-wRotDPa3u1@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-111327-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111327 --- Comment #6 from Jiang An <de34 at live dot cn> --- It seems that deleted operator() overloads in the return type of std::not_fn is only necessary since C++20. The changes were made in P0356R5. In C++17, the return type was nearly fully specified and didn't have deleted overloads. https://timsong-cpp.github.io/cppwp/n4659/func.not_fn#1
