[Bug c++/119060] [C++26] P1494R5 - Partial program correctness

2025-09-02 Thread iains at gcc dot gnu.org via Gcc-bugs
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=119060 --- Comment #3 from Iain Sandoe --- I think we should just add P3641 to this BZ, since it's just changing the name - the functionality is the same. I have a patch for P1494 that has the old name, so will update that to the revised one and post.
