书中没有将重写（override）和重载区分清楚，该用重写进行描述的地方，翻译全部都是用重载来表述的。重写和重载有本质上的区分：对基类标记为virtual的方法，在子类中相应的用override标记的，叫重写，而重载是指方法的标识符相同，参数数量或者类型不同的叫重载。

对于委托的翻译，一会翻译成代理，一会而翻译成委托，代理在语言中是有别的意思的，这样真的不好。

这里吃屎的翻译将原文的decimal翻译为小数，decimal也有十进制的意思

这里根本就不是接口的意思，吃屎的翻译将原文的inference翻译成了接口。是推断的意思。

吃屎的翻译！原文如下： Our Stack class can implement both IPushable and IPoppable—despite T having opposing variance annotations in the two interfaces! This works because you can exercise variance only through an interface; therefore, you must commit to the lens of either IPoppable or IPushable before performing a variant conversion. This lens then restricts you to the operations that are legal under the appropriate variance rules. This also illustrates why it would usually make no sense for classes (such as Stack) to be variant: concrete implementations typically require data to flow in both directions.

翻译的意思和原文的意思简直就是毫无关联！将variance翻译成协变了。第二段的意思本来是说将类设计成可变的（协变或逆变）是没有必要的。

原文是：A delegate merely calls a method on someone else’s behalf. In this case, the String Action is invoked with an argument of type string. When the argument is then relayed to the target method, the argument gets implicitly upcast to an object.

merely 不是很少的意思，我想请问翻译这本书的人，什么叫做委托很少替其他人调用方法！！！！！！！！！！！！！！你们翻译这本书的时候你家里死人了吗你着急成这样？

这个是描述委托的返回类型的时候翻译的一段话，原文是： If you call a method, you may get back a type that is more specific than what you asked for. This is ordinary polymorphic behavior. For exactly the same reason, a delegate target method may return a more specific type than described by the delegate.This is called covariance. 在你翻译大于和小于之前，请你先表述清楚什么是大于，什么是小于好吗？more specific是大于的意思吗？
