That is definitely wrong.
It will get an error for this code if address sanitize is enabled.
```c++
#include <iostream>
#include <utility>
template <class T>
auto f(T &&t) {
return [&]() {
return std::forward<T>(t);
};
}
struct S {
int v;
};
int main() {
auto fn = f(S{.v = 1000});
std::cout << fn().v << "\n";
}
```
