为了理解其中的原理，我们必须简要了解解析器组合子的实现。

To understand how this all works, we have to take a brief dive into the parser combinator implementation.

“组合”解析器可以提供解析概念的越来越高级的抽象(因此称为“解析器组合子”；组合在一起的元素提供解析行为)。

Parsers "combine" to provide higher and higher levels of abstraction over the concept of parsing (hence the name "parser combinators"; elements which combine together to provide parsing behavior).

本文到此结束。在下一篇文章中，我们将回顾scala的更多语言功能(比如泛型，因为解析器组合子是由它们组成的)。

That's it for now; in the next set of articles, we'll go back to visiting more of Scala's language capabilities (such as generics, because parser combinators made use of them).
