Recently, our technical fellow Herb Sutter spoke at a meetup with C++ London to discuss C++’s next decade. Herb discussed the exciting times ahead for C++, as C++26 is poised to do what C++11 did over a decade ago: usher in a new era of C++ code style. After his talk, attendees had the opportunity to connect and discuss what they’d learned. This week, he was the keynote speaker at C++ on Sea, where he shared his thoughts on three key things in C++: features that make our code safer and faster just by recompiling as C++26, reflection as the major game-changing feature of C++26 and the C++26 async framework std::execution.
