church-list: Lazy lists with O(1) concatenation that, unlike dlists, allow inspection
Data.List interface for lists built around the type
r. Monoid r => (a -> r) -> r. This allows for O(1) concatenation and snoc,
just as difference lists do, but without requiring that every operation
(such as map) render the list.
As motivation: Although difference lists are great for use with Writer, they are horrible for use with State, because getting the list and querying an element will result in producing a structure which is thrown away. With mlists, you can both append to, and inspect, the list in progress without any wasted work.
