struct S
{
    int val;
}

auto get = (ref S s) => s.val;  // returns rvalue, not usable for our case

ref get = (ref S s) => s.val;  // Error: variable `test.get` only parameters or `foreach` declarations can be `ref`

void main ()
{
    S s;
    s.get() = 10;
}

It's:

    auto get = ref (ref S s) => s.val;

Closing as invalid.
