After reading the current MEAP I strongly feel that the quizzes make the text a) harder to read and b) don't help comprehension because they break the flow of the reader.

Did you evaluate alternatives to the quizzes? E.g. replacing things like the attached example quiz with a simple paragraph

Listing 1.4 is closer to the functions definition because it makes Account an immutable abstraction

Thanks a lot for the feedback. I am aware that the current format is not the most reader-friendly. And I am still experimenting with a few options. I went through your suggestion and it looks quite good. I have also started introducing a few exercises (programming problems), which you will get in the next MEAP.

Hopefully we will have something that doesn't disturb the flow of the reader.

Thanks.
