|> set 7

This is used in elm-paginate.
This is a very simple package with the express purpose of moving the logic of bounds-checking into a data structure to make your code more concise and clear. See more about "Adding behavior with types instead of logic in Elm" in this video demonstrating a novel use of this package: https://www.youtube.com/watch?v=DxCca6_wdwI.
