Thanks! So, maybe this should also be valid, but more arguable if requires
dip1000 internal checks the same way with `ref`, although, spec-wise it should:

```
void main() @safe
{
    foreach(e; new int[1])
        int* f = &e;
}
```

I removed the `ref`, `f` doesn't escape its own scope, the same way this should
compile:

```
void main() @safe
{
    int e;
    int* f = &e;
}
```
