SRFI 197 is now in final status.Many functional languages provide pipeline operators, like Clojure's -> or OCaml's |>. Pipelines are a simple, terse, and readable way to write deeply-nested expressions. This SRFI defines a family of chain and nest pipeline operators, which can rewrite nested expressions like (a b (c d (e f g))) as a sequence of operations: (chain g (e f _) (c d _) (a b _)).
