As for me I have to see potential problems with []
As you know it can easy make hard bugs if you apply it to pointer.

    Cursor* curs;

    curs[i]  // BIG BIG ops

No, this is not good.

Problem is that then you will at least TRY go to index record many times in
loop.

So I think it is still more safe and effective to use operator()
