一般使用场景： 多个返回值处理
最多支持10个元素：
- Unit<A> (1 element)
- Pair<A,B> (2 elements)
- Triplet<A,B,C> (3 elements)
- Quartet<A,B,C,D> (4 elements)
- Quintet<A,B,C,D,E> (5 elements)
- Sextet<A,B,C,D,E,F> (6 elements)
- Septet<A,B,C,D,E,F,G> (7 elements)
- Octet<A,B,C,D,E,F,G,H> (8 elements)
- Ennead<A,B,C,D,E,F,G,H,I> (9 elements)
- Decade<A,B,C,D,E,F,G,H,I,J> (10 elements)
常用的2元组Pair：
- KeyValue<A,B>
- LabelValue<A,B>
