"Last week, I attended the fall 2024 meeting of the ISO C++ standardization committee in Wrocław, Poland. This was the fifth meeting for the upcoming C++26 standard and the feature freeze for major C++26 features. For an overview of all the papers that made progress, read Herb Sutter’s trip report. Contracts and profiles are the big ticket items that made the most progress this meeting. Contracts is forwarded to wording review, while still being fiercely opposed by some. Profiles is essentially standardized static analysis to improve memory safety, although some deem it ineffective. Due to various scheduling conflicts I did not attend any of the relevant discussions in these spaces. Instead, I am going to share my thoughts about ranges, relocation, and reflection."

"Probably the two most useful features added to C++20 are requires and requires. They make it so much easier to control overload resolution, and when combined with if constexpr in C++17, they allow basic reflection-based optimizations in templates. While requires requires has gotten a lot of (negative?!) press for controlling overload resolution, its cousin requires { requires } is a bit overlooked."

"Two weeks ago, I attended the summer 2024 meeting of the ISO C++ standardization committee in St. Louis, USA. We made progress on a lot of features for C++26, but I have some thoughts about senders/receivers, reflection, and the idea of introducing borrow checking to C++."

"Last week, I’ve attended C++Now 2024 and it was definitely one of the best conferences I’ve ever been to!"
