I suspect that there's a grab bag of things that happen in those one liners, and whether they are a good idea or not depends on the details. For instance, <$> seems pretty helpful, but I shudder when I see flip. I'd go out on a limb and speculate that even for experienced readers, flip is going to be a bit difficult to parse. But I'll have to come back to that when I have more experience.
