I have just started looking at Kotlin, I have been using F# on .NET for a while now and I am liking Kotlin. I am missing pipe operator in Kotlin though, is there any plan to bring the pipe operator to Kotlin?

Why do you need the pipe operator? It may be idiomatic F#, but it's not idiomatic Kotlin. Doesn't extension functions and method-call-chaining kind of solve the same problem?

[marstran]

Like, instead of this in a language with the pipe-operator:

list |> map f1 |> flatMap f2

You would just do list.map(f1).flatMap(f2) .

There are no plans as I know, and there is no proposal for this

[gildor]

Maybe you could show some example of typical usage which you missed in Kotlin, I'm really curious how different it is comparing to F#

Kotlin has two features that mike piping much less needed:
1. Kotlin has extensions, which usually let you "pipe" things directly in a natural .call style, e.g. collection.filter {...}.map{...} (no need for a pipe here)
2. Kotlin has .let scope function that covers the case for non-extension functions, e.g. collection.first().let { println(it) }
