Came across this yesterday as well, its says

_, __ and ___ are reserved

or something.

Yeah, it'd be nice

Maybe a soft keyword to indicate that the parameters are being used for a function reference?

Like with tail recursive functions you have tailrec, why not lambda?

Well I'd rather just be able to use

_

, in my case it came up when overriding something.

Yeah that's another good example

Wait its says the proposal is implemented?

Wut

I just tried it in Kotlin 1.2.40

Nada

Sorry

31

Oh I see

backticks

Apparently not

It's also from 2016.

True

Looking through other props, found this beaut https://github.com/Kotlin/KEEP/blob/master/proposals/destructuring-in-parameters.md

I'd love this

Kotlin 1.2.41 has been in Maven Central since Friday – and a new IDE Plugin is also available. Does anybody know why this hasn't been announced anywhere?

Hi guys, long time listener, first time caller. I’m a little confused by generics in Kotlin. As per my example I want to create a RedDoorHouse, but what do I need to do in House so that it does not need or care to know about the color of the door? In the example I use <?> which is not valid in Kotlin, but it something that would have worked in Java.

A file was commented on

Nice, thanks

Is there an ideomatic way to do this:

private fun kwargs(vararg args: Pair<String, Any?>): Map<String, Any> =
			args.filter { it.second != null }.toMap()

toMap

currently gives me

Map<String, Any?>

...

I think

filterNotNull

might be the way to go

you probably want

mapNotNull

or

mapNotNull { it.takeIf { it.second != null } }

, if you please
