<pre>
    In this example, `foo()` doesn't forward `y`, but clang-tidy doesn't report it.

If none of the parameters are forwarded (comment the `use(std::forward<X>(x));` line), then `cppcoreguidelines-missing-std-forward` correctly reports both parameters as non-forwarded. But if one of them is forwarded, then the other one is not reported.

```c++
#include <utility>

template <typename X>
void use(const X &x) {}

template <typename X, typename Y>
void foo(X &&x, Y &&y) {
    use(std::forward<X>(x));
 use(y);
}
```
