SUMMARY There are no neither highlighting nor tooltips for C++ concepts in the code. STEPS TO REPRODUCE #include <concepts> template <std::integral T> T foo(T) { } OBSERVED RESULT "std::integral" is not colorized and there is no tooltip for it. Same applies to user-provided concept definitions. EXPECTED RESULT At least highlight it as a boolean variable.
