Hi @zeyi2, I chose separate test files per standard (redundant-lambda-parentheses.cpp for C++17, -cxx20.cpp for C++20, -cxx23.cpp for C++23) similar to readability-trailing-comma. Using -std=c++17-or-later in the base file would cause unexpected warnings from the C++23 specifier cases, which are intentionally isolated in the cxx23 file. Happy to change the approach if you prefer a single file.
