it looks dense but perfectly readable. arguably more readable that way than if it had a bunch of extra new lines, definitions, and code blocks spreading the logic out into a larger visible area.
I'm inclined to agree. While not always appropriate or popular, it makes some sense to me to have the visual weight/area of the code being ~proportional to it's significance. Communicates the ideas more clearly. Instead of spending the majority of space telling me what _isn't_ going to happen, and hiding what is.
I often find myself wishing this was more ergonomic in languages.
