// This tests if container forwarding is correctly disabled. If it isn't
// disabled it causes a compile error (which causes the test to pass).
// If it is disabled it tries container forwarding. If it doesn't work
// then there will be a compile error, indicating that it is correctly
// disabled. But if there isn't a compile error that indicates that
// container forwarding might work.
//
// Since this test only tries std::vector, it might get it wrong but I didn't
// want it to fail because of some incompatibility with a trickier class.
