There is a nice pshat from Rebbi Yonathan Eibshutz that, I heard, he said at his bar mitzva. He had two questions, Rebbi Yishmoel Omer, the name Yishmoel and that why it does not say Omar Rebbi Yishmoel as there is no argument on it? We know that Yishmoel did teshuva because he allowed at Avraham’s burial to precede Yitzchok, but the question is, that the Torah is not concerned with the order in the pasuk? If that is case then you cannot darshen a kelal uprat as the in Pesochim questuons, so in the same pasuk order matters and we can darshen a kelal uprat and Rebbi Yishmoel was named properly. Therefkre, from his name he was able to deduce to darshen a kelal uprat.
