How do you define an array of funs(functions) in Kotlin?

How do you define an array of funs(functions) in Kotlin?

This is my assumption of how it would be done...

this.funs = arrayOf : Unit(
    this::openCamera,
    this::sendSMS,
    this::makeCall
        )

How would I invoke each array item as a function at runtime? Would simply specifying 'funs' in place of either openCamera(), sendSMS(), and MakeCall() in a forEach() loop work?

or.. is this the way that I would invoke each function:

val function = getFunction(funs)
function()

If you had some functions defined as

fun one()   { print("ONE") }
fun two()   { print("TWO") }
fun three() { print("THREE") }

Then you can create an array of these as

fun someFun(){
    val arrayOfFunctions: Array<() -> Unit> = arrayOf(::one, ::two, ::three)
    arrayOfFunctions.forEach { function ->
       function()
    }
}
