<pre>The following valid translation unit
```
namespace foo {
template<typename>
struct indirect_int {
using type = int;
};
struct s {};
void operator+(s, int);
template<typename T>
void operator+(typename indirect_int<T>::type, T);
void test() {
s() + 1;
}
} // namespace foo
```
is rejected with the message
```

of class or enumeration type
void operator+(typename indirect_int<T>::type, T);
^
<source>:16:6: note: in instantiation of function template specialization
'foo::operator+<int>' requested here
s() + 1;
