Of course the constructors of classes should be able to access this, and default parameters are evaluated in a constructor.

[Pavlo Liapota]

class Person(val name: String) {
    constructor() : this(this.fun1())
    
    fun fun1() = ""
}

Gives: Cannot access '<this>' before superclass constructor has been called 🙂

This is not the same. It is purely linking outer source to the inner state, this is what Kotlin's feature of defining properties in the very constructor is for. But imagine the following:

class StateSensitive(
  val someVal: Int = this.getState()
) {

  private val state = 2

  fun getState() = state
}

It's quite rough, but speaks for situation pretty much. state will be initialized after the resolution of someVal, so you can't access it, but still do.

There is no "outer" at all, default parameter are evaluated in the class.

[Egor Trutenko]

If you instantiate a field with a value, which was supplied in constructor parameter, then the latter is pretty much "outer"

[Pavlo Liapota]

But why would you like to access this anyway? Potentially no field will be initialized at this point.

Exactly ^
