It can even be done inside the template:

-----
template expand(alias array, size_t idx = 0)
    if (isStaticArray!(typeof(array)))
{
    static @property ref Delay(alias arg, size_t idx)() { return arg[idx]; }

    alias Array = typeof(array);

    static if (idx + 1 < Array.length)
        alias expand = TypeTuple!(Delay!(array, idx),
                                  expand!(array, idx + 1));
    else
        alias expand = Delay!(array, idx);
}
