given

class Foo {
  class Bar { 
    class Baz : Bar()
  }

  fun Bar.Baz.funName() { /* ... */ }
}

this or this@Baz can be used to refer to the Baz (and this@Foo is used to refer to the parent)
however this@funName can also be used for Baz, what's the rationale here? that's kind of strange.

This situation is a bit special because your method has 2 receivers: an instance of Foo, because funName is a method of the class Foo, and an instance of Baz because funName declares Baz as a receiver.

Note that the Bar nesting is irrelevant for this question, by the way, and so is declaring `Bar`/`Baz` inside Foo. It's not about the nesting of the classes, but just about referring to the correct receiver.

The example works just as well when expressed this way, which might makes things clearer:

class Foo {
    fun Baz.funName() { ... }
}

class Baz

Now, this is the same: still 2 receivers, instances of Foo and Baz. I don't know exactly why both syntaxes are allowed for Baz , but I imagine you can use the function name becauss this receiver is declared on the function itself (unlike Foo which is present for all methods of the class)

thanks, that's quite helpful.
