I was about to try to talk about the genuine elegance of Applicatives—and I'm more than happy to defend them in general—but then, yeah. In this instance, I'm not sure I'd be able to argue that the change was such a good choice. liftIO (liftA2 (,) randomIO getCurrentTime) Eh, I'm not sure I could defend it. I'd honestly probably actually do bid <- liftIO randomIO now <- liftIO getCurrentTime
