The following seemingly valid code
```
#include <iostream>
#include <utility>
template<typename F>
auto make_lambda(F&& f)
{
return [f = std::forward<F>(f)] { f(); };
}
int main()
{
auto g = make_lambda([] { std::cout << "hello\n"; });
g();
}
```
results in the error
```
repro.cpp:5:22: error: forwarding reference parameter 'f' is never forwarded inside the function body [cppcoreguidelines-missing-std-forward,-warnings-as-errors]
5 | auto make_lambda(F&& f)
