C++20 Templates - the Next Level: Concepts and More
summary
Walks through C++20 features with concrete code: converts a variadic add implementation from SFINAE to Concepts using a reusable edible concept and tested it with static_assert plus small template stubs, shows requires expressions that check operator+, noexcept and return type, demonstrates abbreviated function templates (no template head), conditional destructor via trailing requires, conditional explicit, NTTPs for floats and class types with a fixed_string NTTP example, and templated lambdas; compiler diagnostics improve and examples compile as shown.
