--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to cqwrteur from comment #0) > The mailing list requires me to request the feature here. I put it here. > https://www.mail-archive.com/gcc@gcc.gnu.org/msg94104.html > "However, I desperately need that feature since current C++ exceptions > are totally unusable." Ridiculous claims like "totally unusable" aren't going to convince anybody. > http://open-std.org/JTC1/SC22/WG21/docs/papers/2019/p0709r4.pdf This is just a proposal, one of many. It hasn't been approved by the committee and is not without critics. It might be suitable to implement in a branch, as a proof of concept, but most G++ developers are already busy working on things that have actually been approved for inclusion in C++.
