Author here. Thanks for your nice comment. I added a note to say it does work with autoformatters too. Actually someone in a comment below said he or she prefers the autoformatted syntax.

Oh, that's good to know! I haven't tried it and assumed an auto formatter might misalign some of it or put things on the same line, so the visual "downward arrow" appearance would be lost

Edit: I just checked the docs again and while it does look a bit "misaligned" at the start, I do think it looks more readable with the autoformatted version. Pretty cool!
