C++23 tools you would actually use
summary
C++23 is stable and the presenter claims only 26% adoption so migration pressure is real; practical wins include richer feature-test macros and std::print in the standard, lambdas and call-operators gaining static and attributes, self-deducing this that removes boilerplate and fixes coroutine lambda-capture bugs, a library generator that cuts ~200 lines to five, and std::expected plus stack_trace for better error handling — but MDSpan still missing from compilers.
