Description

A simple Monoid transformer that takes a Monoid m and produces a new m-Reducer named Self m

This is useful when you have a generator that already contains monoidal values or someone supplies the map to the monoid in the form of a function rather than as a Reducer instance. You can just getSelf . reduce or getSelf . mapReduce f in those scenarios. These behaviors are encapsulated into the fold and foldMap combinators in Data.Monoid.Combinators respectively.
