If a type t is Traversable then values of t a can be split into two pieces: their "shape" and their "contents": data Traversed t a = Traversed { shape :: t (), contents :: [a] } where the "contents" are the same as what you'd "visit" using a Foldable insta...

List comprehensions can also draw elements from multiple lists, in which case the result will be the list of every possible combination of the two elements, as if the two lists were processed in the nested fashion. For example, [ (a,b) | a <- [1,2,3], b <- ['a','b'] ] -- [(1,'a'), (1,'b'),...
