<pre>The following (as far as I know) legal C++03 code does not compile in
-std=c++03 mode, because clang automatically invokes the rvalue reference
extension.
#include <cstdio>
struct T
{
operator T() const { return *this; }
T operator +() const { return *this; }
};
void operator &&(T (T::*)() const, T)
{
std::printf("operator && called\n");
}
int main(int, const char *const *)
{
&T::operator T && +T();
return 0;
}</pre>
