However, Elias has to be careful. As some developers have discovered, using auto without specifying it as a reference (like auto& ) can sometimes lead to the compiler making a of the data instead of just looking at the original, which can cause performance issues or bugs in "convenience gone wrong" scenarios.

By using auto , Elias’s code becomes:
