关于phantom type的一个简陋的kotlin的例子，作用如main所示

	fun main(): Unit = with(SomeBuilder) {
	SomeBuilder.getBuilder().setS2("2").setS1("1").buildSome() // ok
	SomeBuilder.getBuilder().setS1("1").setS2("2").buildSome() // ok
	SomeBuilder.getBuilder().setS1("1").buildSome() // error
	SomeBuilder.getBuilder().setS2("2").buildSome() // error
	SomeBuilder.getBuilder().buildSome() // もerror
	}

	class Some(val s1: String, val s2: String)

求该程序的运行结果。（保证都是下划线，不是什么其他的看起来像下划线的字符）（嘻嘻~）（逃~

	fun main(args: Array<String>) {
	println(吔屎啦下划线地狱(127, 127, 128))
	}

	fun 吔屎啦下划线地狱(______________: Int?, ____________: Int?, _____________: Int?) = ______________ === _____________


	// 这道题目利用了超长的下划线名称和 Java自动装箱的破事以及出题者对回答者的诱导(如果有的话) 糊弄眼球转移注意力。
	// 答案很简单：

Haskell as Kotlin

	import Option.Some

	fun main(args: Array<String>) {
	println(Some({ a: Int -> a + 3 }).apply(Some(2)))
	// => Some(5)

	println(Some(2).apply(Some({ a: Int -> a + 3 })))
	// => Some(5)

	val array = arrayOf<(Int) -> Int>({ it + 3 }, { it * 2 }) apply arrayOf(1, 2, 3)
