(OT: the online translator gave "ballyhoo" for the Dutch "stemmingmakerij", but I doubt that's a proper expression. I just mean to say that the word, as used in that sentence, reads as the view of the writer, which I think we should try to prevent.)

Section 3.22 Arrow operator:

This syntax is particularly helpful when conventional function call syntax is unreadable...

I prefer something like:

This syntax is particularly helpful when conventional function call syntax may make code harder to read....

Perhaps I'm a bit over-pedantic, not a big deal I guess, but I find "unreadable" quite strong, besides, we have lived with this older syntax for over a decade and managed quite well ;).
