Universal/Forwarding References in C++ - From C++11 to C++20

Dive into the intricacies of universal/forwarding references in C++ with this comprehensive conference talk from Meeting C++ 2022. Explore how T&&, auto&&, and decltype(auto) have evolved from their introduction in C++11 to become key features in various C++ programming scenarios. Learn about their initial purpose for perfect forwarding of move semantics and their expanded role in implementing range-based for loops. Discover the importance of universal references in C++20 for writing generic code that works seamlessly with both containers and views. Gain valuable insights from expert Nicolai Josuttis as he provides a detailed examination of these powerful language features, equipping you with the knowledge to leverage them effectively in your C++ projects.
