Oh, weird. I remembered the Ruby range operators when I read about Swift’s and assumed Ruby was the inspiration; but then why do them the other way around?
(But to me, it makes more sense that three dots would give you a bigger range than two dots. Shrug.)
Historically, the IBM 704/709 computers did quotient/remainder wrong. I’ll bet the Burroughs B5000 got it right, though. As we all know here, the B5000 did everything right. ;-)
