Example:
fun someFunc(n:Int):Int{
return n
}
fun mainFun(fun:()->(Unit)){
printnl(fun(4))
//Should print out 4
}
mainFun(someFunc)
Is that possible, and when how?

Yes, you can use function references. Note that type of the function has to match type of the parameter
fun someFun(n: Int): Int {
return n + 2
}
fun mainFun(f: (Int)->Int) {
println(f(4))
}
fun main() {
mainFun(::someFun)
}
Thank you.
