Been trying out C++ auto in a few different places and use cases to see how it feels and whether we want to use it more. Prevailing opinion in my team is clear: auto harms readability, comes with unwelcome gotchas, and is generally irritating. Very on brand for C++ though.

I've just had a bug caused by an auto, I was expecting a ref, the deducted type wasn't a ref :( Ironically sometimes auto requires to be more cautious.
This used to be my issue with auto, till I realized that if I had wanted a copy, and auto deduced a ref type, there would be no syntax for getting a copy. Use auto& for reference. Use auto for copy.

And for funzies, if the type returned is a const ref, auto&& will work, while auto& will not. Of course, const auto& would also work. The one thing I had to really work at was pointers. Those are by copy, even though in my head they are references.
Kiitos. Käytämme tätä aikajanasi parantamiseen. KumoaKumoa

auto c = std::copy(x); auto r = std::ref(x); … … … Yeah
