The `cppcoreguidelines-missing-std-forward` clang-tidy triggers a warning on the example from the docs, where it should be fine.
Reproducer:
```c++
#include <utility>
template <typename T>
void impl(T);
template <class T>
void wrapper(T &&t)
{
impl(std::forward<T>(t), 1, 2); // Correct
}
```
Expected result: No warning produced
Actual result:
```
> clang-tidy --checks=-*,cppcoreguidelines-missing-std-forward test.cpp --
1 warning generated.
D:\projects\CVUT-FEL\bp\experimental\vision-sim3d\test.cpp:7:18: warning: forwarding reference parameter 't' is never forwarded inside the function body [cppcoreguidelines-missing-std-forward]
7 | void wrapper(T &&t)
| ^
```
This issue occured on Windows on both 20.1.0 and the current version. I was not able to reproduce this issue on other platforms. Furthermore, when using clangd in editor, it handles the check correctly.
```
> clang-tidy --version
LLVM (http://llvm.org/):
LLVM version 22.1.0
