I have the following code example: ```d struct A{}A[5] a; ulong[] idx = [1,3,4]; auto get() { return idx.map!(_ => a[_]); } foreach(i; 0 .. a.length) write(&a[i], " "); writeln; foreach(ref b; get()) write(&b, " "); writeln; ```How can I change `get` function so it returns the references to the content in `a`?
Have the lambda return by reference: ```d auto get() { return idx.map!(ref (i) => a[i]); } ```
