I think we'll see it as soon as 1.6.20 as a preview feature (e.g. behind a compiler flag)

Nice!

What theme are you using for your IDE?

I like really this feature, But the syntax kinda throws me off

That would be awesome, because I could put this to use immediately if IntelliJ had language support for it.

It's a bummer you can't change IntelliJ Kotlin compiler version outside of distributed options.

Fingers crossed! 🤞

@therealbluepandabear The theme is the Jetbrains port of "Plastic" =)

Same, especially the double indenting with

Practically speaking, you probably wouldn't be using with as it is mainly just there to set up the scope properly for testing. In a real world example, setting up a Ktor route would have you in multiple nested scopes in which you could set up a function for (e.g. being able to reference both Application and Route in the same extension function without needing to explicitly pass either instance).

For example, this:

fun doSomething(application: Application, route: Route) { /* ... */ }

could be condensed to:

context(Application, Route)
fun doSomething() { /* ... */ }

And thus the caller would not need to explicitly pass either instance. At least, that is my understanding.
