--- Comment #18 from Michel Morin <mimomorin at gmail dot com> --- Thanks, much appreciated! (In reply to Jonathan Wakely from comment #17) > That's how new features work. If you want to use them, you need the new > version. The time for adding new features to GCC 9 was last year. Agreed in general. If this was a C++2A feature, I would not ask for releasing it in a hurry. New features should be tested enough and we developers can test/use the feature with a gcc-trunk snapshot. (I made this backport request because I (mistakenly) thought that this was a small fix and not a new feature.)
