import samples.assertPrints
import kotlin.concurrent.thread

fun main() { 
   //sampleStart 
   val answer: Lazy<Int> = lazy {
    println("Computing the answer to the Ultimate Question of Life, the Universe, and Everything")
    42
}

println("What is the answer?")
println(answer) // Lazy value not initialized yet.
println("Oh, now compute it please")
// Will print 'Computing...' and then 42
println(answer.value) // 42
println("Come again?")
// Will print 42
println(answer.value) // 42 
   //sampleEnd
