Trivia question: how many receivers can a single function have, without using context receivers?

One is easy, it's just a regular top-level extension function.
Two is a bit harder: it's an extension function declared in a class.

Is it possible to do more? I thought about inner classes, but those have implicit access to their outer class, it's not really an additional receiver since it isn't sourced from the callsite.

Do local functions count?

fun Cxt1.one() {
  fun Cxt2.two() {
    fun Cxt3.three() {
      fun Cxt4.four() {
        fun Cxt5.five() {
          println(p1)
          println(p2)
          println(p3)
          println(p4)
          println(p5)
        }
      }
    }
  }
}
