Three Cool Things in C++

It's 2025, and C++ is vibrant and growing! The next standard's feature set should be finalized about 48 hours before this opening talk of C++ on Sea 2025, and there's a lot going on with new safety and modules improvements in real-world compilers and standard libraries. The aim of this talk is to cover just a few of these things well, and to go deeper than just-the-facts (what it is) but also delve into context (why it matters, where it's leading) and practical applications (how to use it, with examples).
