Kotlin Return with Labels

snippet.kt

val list = listOf("Kotlin", "", "Java", "Groovy")

fun main() {  
  list.forEach {
    if(it.isNullOrEmpty()) return@forEach  // return with implicit label
    println(it)    
  }
  println("Done!")
}

// equivalent to:

fun main() {
  list.forEach there@{ str -> 
    if(it.isNullOrEmpty()) return@there  // return with explicit label
    println(str)
  }
  println("Done!")
}
