Even this comment is technically true that are really not the things you should start with in programming classes, imho. Having already some experience with other similar but simpler things will enable the students to pick up later on those more advanced things more quickly with less effort, and especially with much less pain. Also things become simpler to teach as more background is already know to the students. Needing to explain "everything" at once is not a simple task. This will cause a lot of confusion usually as people don't have yet the proper mental models to sort things into. It becomes harder to actually teach things. My point is: Lessons in itself shouldn't be "the worthiness test". The goal is to teach people programming, not torture them. You can test and verify the understanding of the things taught in the next step. Also it's in general much simpler to teach things along a structure where you go form the big picture gradually down to the details instead the other way around — otherwise people may not see the forest for the trees for a long time. Needing to much details only to get basic things going will cause confusion and a lot of unnecessary frustration in my opinion.
