I addressed those points implicitly. Those names are meaningful, in context, to the people who understand the language; just as symbols in math are, in context, understandable to those who understand mathematics. And thus there is no need for comments. Arguably, there are too many comments, because I saw many that said something obvious without adding anything useful. Short identifiers aid reading for people who understand the language, because it allows them to focus on what the code does (or, rather, how exactly it does it) rather than what the things in it are (which is obvious to people who understand the language).
