If I’m not mistaken, those make use of the unwrapped reader monad? In my opinion, that is an instance that is confusing and unidiomatic to many people. I don’t think that “easy to write with unwrapped reader” is the same as “easy to write” (or “easy to understand”). I wouldn’t want core docs to recommend this as an approach. 

I agree with Gershom.
