Kotlin documentation只描述了在访问Java和enum类中的克隆.在后一种情况下，克隆只是抛出一个异常.
So, how would I / should I clone arbitrary Kotlin object?
Should I just use clone() as in Java?

对于data class，您可以使用编译器生成的copy() method.请注意，它将执行浅层复制.
To create a copy of a collection, use the toList() or toSet() methods, depending on the collection type you need. These methods always create a new copy of a collection; they also perform a shallow copy.
对于其他类别，没有特定于Kotlin的克隆解决方案.如果.clone()适合你的需求，你可以使用它，如果不适合，你可以构建一个不同的解决方案.
