ajvengo / copy_vs_move_test.cpp

Created April 7, 2017 19:49

Test copyable vs movable arguments for overloaded functions

	#include <type_traits>
	#include <iostream>
	using namespace std;

	// must be used for movable arguments only
	void f(int&& x) {
	using X = decltype(x);
	cout << __PRETTY_FUNCTION__ << ' ' << std::is_rvalue_reference<X>::value << endl;
	}
