As long as it is not actually removed, it is not too late to undo this totally incorrect decision.See also:https://valdyas.org/fading/hacking/happy-porting/ (Technically, it could be readded even after it is removed, but it would be much easier to undeprecate it now.)
Please bring technical arguments to the table for undoing this deprecation. So far, this hasn't been done, so the deprecation stands and likely go into effect the first time we get a chance of breaking SC.
Note that "annoyance for end-users" is not an argument. In the absence of infinite development bandwidth, and given the natural evolution of software, Qt will need to shed some old crust from time to time, even if that means annoyances for the users.
I briefly discussed about this here:
https://www.kdab.com/un-deprecate-qt-project/
Specifically for Q_FOREACH, if a project doesn't want to move away, then the solution takes 5 minutes:
1) copy and paste Q_FOREACH's implementation in a central header of your project
2) rename it to MY_FOREACH3) do a search/replace of Q_FOREACH to MY_FOREACH throughout the project's code base
And that's it.Yes, this is effectively a fork, which means you'll also need to backport any fixes that in the meanwhile land upstream. And they _do land_, even for something apparently as "mundane" as Q_FOREACH:
https://codereview.qt-project.org/#/c/179396/ https://codereview.qt-project.org/#/c/176299/ > https://codereview.qt-project.org/#/c/176298/ https://codereview.qt-project.org/#/c/170073/ https://codereview.qt-project.org/#/c/167065/ https://codereview.qt-project.org/#/c/140268/
Why should the Qt Project invest any resource whatsoever maintaining a solution to a problem that has also been solved by the C++ language (and in a more efficient and general way than Q_FOREACH)?
