This is so good. I would love this kind of "learning" for every language. It's definitely not beginner friendly but for anyone that already knows a language this is a super introduction and quick start, maybe even tipping point to start using the language. Only remark: If I had anchor tags at specific points creating a reference would be easy, this is referenceable material. Great job though, I am amazed at the quality of this. Hell yeah!
