Coincidentally: (?) https://bugzilla.mozilla.org/show_bug.cgi?id=1280296 "remove already_AddRefed" :-)
For your original question, I would vote for RVO when possible, and Move() otherwise. It feels like static analysis should be able to detect cases where RVO is possible and suggest it if missing; and also detect cases where it's not possible and warn about a missing Move(). _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
