In this example traverse_raw_set doesn't even compile.

#include <iostream>
#define SOL_ALL_SAFETIES_ON 1
#define SOL_PRINT_ERRORS 1
#include <sol/sol.hpp>

int main() {
    sol::state lua;
    lua.open_libraries();
    lua.create_table().traverse_raw_set("a", "b", "c");
}

Source code:

	constexpr static bool global

	return *this;

template <typename... Keys>

	return *this;
}

Is there a reason they are different? The only thing that should change is raw template parameter to true.
