```cpp
#include <optional>
int main() {
struct S { int x; int y; };
auto a = std::make_optional<S>({1, 2});
}
```

This function is equivalent to: `return optional<T>(in_place, il, std::forward<Args>(args)...)`;
So it shouldn't participate in overload resolution because the `optional`'s constructor constraint is not satisfied?
