Explore how C++20 simplifies std::tuple implementation in this ACCU 2019 conference talk. Dive into the application of new language features like Concepts, attributes, and extended syntax to create a high-performance, optimized implementation with minimal complexity. Learn about the evolution of std::tuple across C++ standards, implementation challenges, and how C++20's features combine to streamline the code. Discover techniques for generic wrapper types, comparison implementations, and the impact of fold expressions, expansion statements, and the spaceship operator. Gain insights from Alisdair Meredith, a former chair of the C++ Standard Committee Library Working Group, on leveraging C++20's capabilities to enhance tuple functionality and simplify development.
