Pipeline operator #39

Open prakhar1989 opened 8 years ago

prakhar1989 commented 8 years ago

Add a pipeline operator to simplify function composition.

OCaml syntax

# let path = "/usr/bin:/usr/local/bin:/bin:/sbin";;
val path : string = "/usr/bin:/usr/local/bin:/bin:/sbin"
#   String.split ~on:':' path
  |> List.dedup ~compare:String.compare
  |> List.iter ~f:print_endline
  ;;

Inspiration - https://docs.hhvm.com/hack/operators/pipe-operator. Good ideas on using $$ as placeholder for capturing output.
