Capture and mutate value of variable outside lambda expression

Is it possible to increment the value of the counter variable in the main function from a lambda?

fun main(){
   var counter = 0
   val incr = { ++counter}
   incr
   println(counter)

Well, you can misuse an anonymous function and hand over the variable that should get modified. But I am not sure that is what you are looking for:

fun main() {
    var counter = 0
    val incr = { _: Int -> ++counter }
    incr(counter)
    println(counter)
}

The output is actually 1.
