Hi,
We encounter performance issues with clang-tidy misc-const-correctness when we introduced std::format.
I tried LLVM 16.0.0, 16.0.3 and 16.0.6.
The file I tested has only one std::format:
const double toto = 1.0;
std::string s = std::format("text I want = {}", toto);
vs
std::string s = "text I want = " + std::to_string(toto);
