    int opApply(int delegate(inout T elem) dg)
    {   int result = 0;

	for (int i = 0; i < arr.length; i++)
	{
	    result = dg(arr[i]);
	    if (result)
		break;
	}
	return result;
    }
    int opApply(int delegate(inout int idx; inout T elem) dg)
    {   int result = 0;

	for (int i = 0; i < arr.length; i++)
	{
	    result = dg(i, arr[i]);
	    if (result)
		break;
	}
	return result;
    }
