Guaranteed Copy Elision deserves some attention!

Guaranteed Copy Elision

by Jonas Devlieghere

From the article:

The new C++17 standard brings many exciting new features. A smaller, more subtle improvement it brings is guaranteed copy elision. The keyword is guaranteed, as copy elision itself has always been part of the standard. Although it might not be a change as radical as, say, structured bindings, I'm very happy to see it made it into the standard.
