Yuck. I’ve already noticed compilation times increasing from C++17 to C++20, and this feature makes it much worse. I guess I’ll need to audit any reflection usage in third-party dependencies.
Please check the article again -- I made a mistake in the original measurements (the Docker image I used had GCC compiled in debug mode) and now the (correct) times are ~50% faster across the board.
Not free, still need to audit, but much better than before. Sorry.
