Otherwise LGTM, thanks! Ludo’.

The way I understand it is: "transformers State monad" stands for the transformer monad called StateT, itself a monad. But I'll let you or a native English speaker decide about the grammatical correctness of the synopsis provided by the author :-) Thanks, Fede

But even after looking at the code I can’t quite make sense of the synopsis :) It provides functions that take accessors and return State and Read-Write-State monad transformers. ~~ Ricardo
