Careful here, you've got the arguments reversed. The unit test 
didn't detect this because it was ambiguous. This one isn't:

    unittest {
        OneBasedArray!int arr;
        arr = [1,2,3];
        arr ~= 14;
        assert(arr.length == 4);
        assert(arr[1] == 1);
        assert(arr[2] == 2);
        assert(arr[3] == 3);
        assert(arr[4] == 14);
    }
