One thing that makes Swift is value semantics Are there any plans of adding this to the language? I presume real value types are a pipedream since jvm doesnt care, but the var semantics is way nicer code than 
.copy
so maybe just the syntax as a sugar?
e
there is some hope for future JVMs, https://jdk.java.net/valhalla/ but it's not ready yet
u
soo nothing until valhalla?
realistically speaking
I'd gladly accept it just as a sugar for copy
btw do you have any info as on what big is coming next other than the new compiler? which sure is great for performance, but not really a language feature, is it

The main focus is on K2 right now, which will also bring some advantages language-wise. You can see what is being worked on in the roadmap: https://kotlinlang.org/docs/roadmap.html

to clarify, the Kotlin language is not changing with 2.0 (aside from minor fixes), only the Kotlin compiler implementation changing to K2

We are consciously avoiding introducing any new features in Kotlin 2.0.

Kotlin's multi-field value classes do not strictly depend on Valhala. You can follow the progress in KT-1179.

While there are no compiler plugins that get your desired semantics via 
var
, there are some cool compiler plugins to make working with immutable data more pleasant. https://arrow-kt.io/learn/immutable-data/intro/
