Get pointer or reference of an element in Array(struct)

[Arun Chandrasekaran via Digitalmars-d-learn]

Is there a way to get the pointer or reference of an element in 
Array(T)?

The assertion seems to fail below. Value copy is not is intended 
here.

module test;

void main()
{
    struct Data
    {
        int id;
    }

    import std.container.array;
    Array!Data gallery;

    Data d1;
    gallery.insertBack(d1);

    auto d2 = gallery[0];
    d2.id = 1;
    assert(d2.id == gallery[0].id, "neither ref nor pointer");
}
