I was careful to pre-empt this exact response in my original comment: I do know what it does. The fact remains that it's less readable (IMO) because of the density of line noise and the lack of common structural elements (like if and for - I suppose filter and map fulfill this but their parameter separate out elements that ought to be next to each other). I do think that my preference, however slight, would remain no matter how much time I spent with the functional versions.

I'm glad you know what it does but you weren't born knowing what the walrus operator does either
