The idea is to provide single for loop structure for each of the variables(in this case s and this).

You can do this with `std.meta.AliasSeq`:

    string[] a = ["lions", "tigers", "bears"];
    int[] b = [123, 456, 789];

    static foreach(array; AliasSeq!(a, b)) {
        foreach (item; array) {
            writeln(item);
        }
    }
