The F# language does partial application through calling the function: if you don't supply enough arguments, they're partially applied. The |> syntax is for "backwards" (object-y) partial application:
let f x y = ... let g = f 1 let h = 1 |> f The |> operator is built-in in F#, but in OCaml (my background), |> can be defined easily enough: let (|>) x f = f x ~~ Robert Fischer, Smokejumper IT Consulting.
