Luabind: Binding an overloaded class function

Consider the following code:

	#include <string>
	#include <iostream>
	#include <luabind/luabind.hpp>
	class overloaded_function
	{
	public:
	overloaded_function() {}
	void print_string() { std::cout << __FUNCTION__ << std::endl; }
	void print_string(int x) { std::cout << __FUNCTION__ << ": " << x << std::endl; }
	};
	extern "C" int init(lua_State* L)
	{
	using namespace luabind;
	open(L);
	module(L)
	[
	class_<overloaded_function>("overloaded_function")
	.def(constructor<>())
	.def("print_string", (void(overloaded_function::*)(int))&overloaded_function::print_string)
	];
	return 0;
	}
