class Thing(parameter: Int) : List<Int> by property { //unresolved reference: property
	val property = listOf(parameter)
}

why isn't this allowed?

Because implemented interfaces and super classes are initialised before Thing and its members.

You can inline that listOf and then retrieve it by casting this to that interface

or add another constructor, class Thing private constructor(val property: List<Int>) : List<Int> by property { constructor(parameter: Int) : this(listOf(parameter)) }
