Reader is like implicit parameters: dynamic scoping with static types. https://dl.acm.org/doi/10.1145/325694.325708

I know what Reader is, but my point still stands.

Okay... I wasn't suggesting you don't know what Reader is... you said:

>Reader is like a middle-ground between dynamic-scoping and explicit passing of a context argument around

I just wanted to point out that the-thing-which-Reader-is, is sometimes called "implicit parameters", and there are papers written about it.
