[PATCH] D45163: [Sema] -Wunused-value: diagnose unused std::move() call results.

[Marshall Clow via Phabricator via cfe-commits]

mclow.lists added a comment.

So.
https://bugs.llvm.org/show_bug.cgi?id=10011 was resolved by https://wg21.link/P0600 (which added `[[nodiscard]]` to `string.empty()`

We can do the same for `move`.
However, I have been promised a comprehensive paper listing all the (100s?) of places in the standard library which should be so marked, and I'm inclined to wait for it (but not for too long).
[ The next WG21 meeting is in June ]
