另一个问题是我们为什么需要治理SOA以及为什么我们以前没有谈过其他技术的治理，如CORBA，和面向对象(OO)设计。
Another question is why we need to govern SOA, and why we have not talked about governance of, for example, CORBA or object-oriented (OO) design?
就像使用对象设计时，我们应当预料到创建可重用的、松散耦合的、面向方面的系统和可重用的、通用的方面库会大量地要求基于接口的技术。
As with object design, we should expect that creating reusable, loosely coupled, aspect-based systems and reusable, generic aspect libraries will require a comprehensive approach based on interfaces.
已经看到了如何把curry过的闭包应用于函数模式，所以现在我们来看看在使用相似的技术重新访问重要的面向对象设计模式时发生了什么。
You've seen how you can apply curried closures to functional patterns, so now let's take a look at what happens when we revisit an important object-oriented design pattern using similar techniques.
