That is a very good argument for controlled large feedback times in a learning environment, also, just some of the time, when thinking about your code is the focus of the exercise.

I'm one if the people that thinks that coding in paper is a great learning task. I tend to not ask people to do that in practice because it's a very effective way to lose control of a classroom, but I do use the second best task that is asking people to explain their code.

Anyway, if thinking about the code is not your focus, the increased feedback cycle is all cost and no gain.
