why?   “*” is infix,  [] is some kind of subscripting matchfix?

But when you have a complex arithmetic expression, the effect is to make it harder to read, because it falls off the end of the line.  So this is something that I would rather leave up to the programmer to consider on a case-by-case basis.

doesn’t mandatory indentation have the same effect?   
in either case, programmers have to break lines in sensible places, or extract methods
