[PATCH] D148505: Allow `__attribute__((warn_unused))` on individual constructors

[Stephan Bergmann via Phabricator via cfe-commits]

sberg added a comment.

> But the fact that these two attributes already confuse users (AND we've got unused as an attribute in the mix as well, which doesn't help) means we should proceed with caution (and likely coordinate with GCC given that all three of these attributes came from their implementation).

I've brought this up at https://gcc.gnu.org/pipermail/gcc/2023-April/241205.html "GCC/Clang attributes guiding warnings about unused entities" now.  (I tried to cross-post that also to the Clang Frontend discourse category, but that probably didn't work.)
