At risk of being pedantic, that's actually shorter. It also doesn't work, at least on the version of OCaml I'm familiar with. In order to invoke that particular bit of "language magic", you'd have to declare it external and explicitly give its type:

    external (|>) : 'a -> ('a -> 'b) -> 'b = "%revapply"

Also, `%apply` is usually the `@@` operator. For `|>`, one would expect `%revapply`.

OCaml, like SML, have the syntax for defining their own operators. |> is defined, to my knowledge, both in the standard prelude and in core.
