Do I really need care about this? I really hoped that I can just not bother wrapping things in std::move and let the compiler figure it out?
I.e. if I have
```
std::string a = "hi";
std::string b = "world";
return {a, b}; // std::pair
```
I always assumed the compiler figures out that it can move these things?
If not, why not?
My ide tells me I should move, surely the compiler has more context to figure that out?
- brooke2k 9mo agoI think there's a consequence difference between the IDE being sure enough that a std::move is warranted to issue a lint, versus the compiler being 100% provably certain that inserting a move won't cause any issues.
- ohnoesjmr 9mo agoSure, but by the sound of the article, the compiler won't do the right thing? Effectively, I'm a c++ novice, should I ever sprinkle move (under the constraints of the article)? Or will the compiler figure it out correctly for me and I can write my code without caring about this.
