To make this all work, I had to remove the stringification cache from matchers. In theory, this can cause performance penalty in cases where single matcher instance is stringified multiple times, but in practice this does not happen much, and the difference is surprisingly small anyway, because the performance of stringification is already horrible and full of allocating strings just to throw them away. The matcher combinators need P2738 from C++26 to be `constexpr`. TODO: close related issues
