Is this correct? The “*" function has the “by” argument label and the “/“ function doesn’t?
    public func multipliedFullWidth(by other: Self) -> (high: Self, low: Self.Magnitude)
    public func dividingFullWidth(_ dividend: (high: Self, low: Self.Magnitude)) -> (quotient: Self, remainder: Self)
(These were copy/pasted from Xcode. There are a couple other differences between the snapshot and the proposal… that’s why the functions’ signatures don’t completely match.)

I glanced over the relevant mailing list threads, but didn’t see any discussion on the matter. Dunno, maybe I just missed it. Anyway, just thought I’d pass along what looks to me like a simple typo.
