将F#管道运算符(< |，>&gt ;、<<)转换为OCaml [英] Converting F# pipeline operators ( <|, >>, << ) to OCaml

问题描述

我正在将一些F#代码转换为OCaml，例如，我看到此管道运算符<|有很多用途:

I'm converting some F# code to OCaml and I see a lot of uses of this pipeline operator <|, for example:

let printPeg expr =
    printfn "%s" <| pegToString expr

<|运算符显然定义为:

# let ( <| ) a b = a b ;;
val ( <| ) : ('a -> 'b) -> 'a -> 'b = <fun>

我想知道为什么他们要麻烦地在F#中定义和使用此运算符，仅仅是为了避免出现这样的括号吗?:

I'm wondering why they bother to define and use this operator in F#, is it just so they can avoid putting in parens like this?:

let printPeg expr =
    Printf.printf "%s" ( pegToString expr )

据我所知，这就是上面的F#代码到OCaml的转换，对吗?

As far as I can tell, that would be the conversion of the F# code above to OCaml, correct?

此外，我如何在Ocaml中实现F#的<<和>>运算符?

Also, how would I implement F#'s << and >> operators in Ocaml?

(|>运算符似乎只是:let ( |> ) a b = b a ;;)
