it infuriated me that Google's style guides forbid this kind of formatting. Anytime someone else tried to get them to allow it it was shouted down as ASCII art
If I'm honest, I like that kind of formatting for small 2-3 line, 2-3 part expressions. But I am not a big fan for it in much bigger parts (like that huge index calculation above). I always see them and think that I'd rather see a loop over an array of values, or split into many smaller expressions.
