Use a object before initialized as other object argument
I'm new to kotlin and I know that nullable are something I should'nt use as much as I would want too. So I was wondering if something like that would be possible.
class Header(var next: Trailer)
class Trailer(var prev: Header)
fun main() {
lateinit var trailer: Trailer
val header = Header(trailer)
trailer = Trailer(header)
}

Thank you for the time used to answer my question!
