Like I said, I never wrote c++ there so I’m quite likely misremembering details, but IIRC the published style guide linked to upthread is more or less a snapshot of the previously-unpublished style guide used internally for internal code. It may have some omissions and it’s quite likely out of date.

I’m just amused that this discussion about semantics reminds me so much of the gif linked from https://news.ycombinator.com/item?id=40882247
