I am also very happy about this; I learned something new, and the explanations felt perfectly clear.
Especially I liked the explanations “from outside perspective”, like lambda notation vs arrow notation, or why the product symbol is used. These things are typically not mentioned in textbooks, because they teach the official notation, but this is exactly what you need as a beginner, to connect what you already know with the new things.
