Is it possible to access the outer class instance for another instance of the current inner class? For example, I want to access

other@Outer.x

here but I can't figure out the syntax:

class Outer(val x: Int) {
    inner class Inner {
        fun foo(other: Inner): Int = this@Outer.x + other@Outer.x
    }
}

Not an answer, but wouldn’t it be simpler and cleaner to do this?

class Outer(val x: Int) {
    inner class Inner {
        private val x get() = this@Outer.x
        fun foo(other: Inner): Int = this.x + other.x
    }
}

Ah that's a nice workaround! I'm not sure if it's cleaner but it beats manually adding an explicit field for the outer class and removing

inner

. Thanks!
