It must return object, but it is in template
i added ref, or witout ref, same
this the part of opApply

int opApply(int delegate(ref T) callback)
{
    int result = 0;
    for (int i = 0; i < _items.length; ++i)
    {
       result = callback(_items[i]);
       if (result == 0)
       break;
    }
    return result;
}
