With C++17, and a third-party library, you can now obtain the name of a class like

#include 
#include "nameof.hpp"

namespace test {

    constexpr auto obj_name = nameof::nameof_type();
    std::cout << obj_name << std::endl;
    // this prints "test::Object"
}

This uses only compile-time information, so it can be constexpr. Note that it’s not portable; for example Intel’s compiler isn’t supported.
