What is happening here? Accessing null inside class???

Question

class Test (var something: String){
// Compiler warns: Receiver parameter is never used
// But it is necessary to let the following work.
val Test?.something get() = "CCC"
fun someMethode() {
var test: Test? = null
println(test.something) // works, prints CCC
println(null.something) // works also, prints CCC
test = Test("BBB")
println(test.something) // now prints BBB
test = null
println(test.something) // now prints again CCC
}
}
fun main() {
val test1 = Test("AAA")
println(test1.something) // prints AAA
test1.someMethode()
val test2: Test? = null
// println(test2.something) won't compile
}

So i wont say Kotlin is my main language but i love the simplicity that it gives to some of the syntax that it uses.
test2.something needs to be test2?.something, you cant set something to a null and expect it not to yell at you when its outside of the class.
