> (2) The 'defer' diagram is a big WTF. Couldn't even figure out which box is supposed to represent which statement in the example.

I found the defer diagram very accurate and understandable, but I already knew what "defer" does.

From the preceding examples, I understand that the little box is an instruction the developer didn't write, but was added automatically. From the graph, I understand that the instructions are executed in a different order from what it's written by the developer (and exactly in reverse order).
