-Scala case classes (and Scala tuples which are a special case of case
classes), are composite types that contain a fixed number of fields with
various types. Tuple fields are addressed by their 1-offset names such as `_1`
for the first field. Case class fields are accessed by their name.
+Scala Case Classe （和指定 case 为 Case Class 的 Scala
Tuple）是复合类型，包含固定数量的各种类型的字段。Tuple 的字段从 1 开始索引。例如 `_1` 指第一个字段。Case Class 字段用名称索引。
