queue container?

[J Arrizza]

I need a Queue (put on the front and pop from the back).  The best I can
come up with so far is:

    Array!string list;
    list.insertBack("a1");
    list.insertBefore(list.opSlice(0,1), "a2");
    list.insertBefore(list.opSlice(0,1), "a3");
    list.insertBefore(list.opSlice(0,1), "a4");
    list.insertBefore(list.opSlice(0,1), "a5");

    while (!list.empty())
    {
        string s = list.back();
        list.removeBack();
        writeln("x: ", s);
    }

Having to insertBack when the list empty and insertBefore with the range,
seems strange to me. Is there a better way?
