#include <utility>
struct A {
template<typename T> void func( T && t ) {}
};
struct B {
void func( int ) {}
};
struct C {
template<typename T, typename U> void func(T && t, U && u) {
//"As is the case with typename, the template prefix is allowed even
if the name is not dependent"
t.template func(std::forward<U>(u));
}
};
