正如我们所见，反射API能够通过现有函数和方法动态创建闭包，从而为闭包提供强大的支持。
The reflection API has great support for closures, as we've now seen, in the form of being able to create them from existing functions and methods dynamically.

I will probably move the function elsewhere within the Gnosis package for later releases.
在Oracle10g 中可以使用包对过程或函数进行分组。
Packages can be used in Oracle 10g to group a set of procedures or functions.
要构建一个使用闭包的函数，只需要使用yield关键字来调用该闭包。
To build a function that USES a closure, you simply use the yield keyword to invoke the closure.
闭包类似于lambda函数，但是在与定义闭包的外部环境中的变量进行交互方面更加智能。
Closures are like lambda functions, but smarter in the sense that they have the ability to interact with variables from the outside environment of where the closure is defined.
当客户端发布connect时，在协议层调用tcp _ out put函数，将SY n包输出到接口。
When the client issues connect, the tcp_output function is called at the protocol layer, which outputs the SYN packet onto the interface.

要使用cURL函数，必须启用PHP环境中的 libcurl包。
To use cURL functions, it is necessary to enable the libcurl package in a PHP environment.
调用函数tcp _ output，将SY n包输出到网络。
The function tcp_output is called, which outputs the SYN packet onto the network.
默认情况下，它们是由值传递的，意味着如果要更新传递到闭包函数定义内的值，则不更新外部值。
By default, they are passed by value, meaning that if we would update the value passed within the closure function definition, it would not update the outside value.
这种情况下返回的函数对象就是一个闭包，其中封装了一些日志代码和最初的函数调用所需要的数据。
In this case the returned function object is a closure which encapsulates some logging code and the data needed to call the original function.
这个闭合的作用域是将闭包同调用函数和定义它的代码联系起来的纽带。
This closed scope is the communication that ties the closure to the calling function and the code that defines it.
如果您测试的是一个函数，而这个函数是一个常见的可添加的软件包的一部分，那么不要告诉用户缺少的函数的名称——告诉用户他们需要的软件包。
If you're testing for a function that is part of a popular add-on package, don't tell the user the name of the missing function — tell the user the name of the package they need.
闭包是函数语言的共有特征之一。
Closures are one of the common features of functional languages.
注释是可以添加到代码中的修饰符，可以用于包声明、类型声明、构造函数、方法、字段、参数和变量。
Annotations are modifiers you can add to your code and apply to package declarations, type declarations, constructors, methods, fields, parameters, and variables.
清单3包含有这个函数，它尝试打开数据库(如果尚未打开的话)并查询数据库。
Listing 3 contains this function, which attempts to open the database (if not already opened) and query the database.
好奇的读者会想是什么使仿函数不同于匿名函数或闭包呢？
Curious readers will be wondering what makes a functor different from an anonymous function or closure.
闭包是具有闭合作用域的匿名函数。
以上演示了为什么闭包体现了函数思想：让运行时管理状态。
This illustrates why the use of closures exemplifies functional thinking: allow the runtime to manage state.
在本文中，我将继续讨论这些概念，讲解一级函数、优化和闭包。
In this article, I'll continue this tour of concepts by talking about first-class functions, optimizations, and closures.
如果使用过高阶函数或闭包，那么可能更容易理解清单10中的代码。
If you've ever used closures or higher-order functions, you might have a better understanding of the code in Listing 10.
如果碰巧该闭包函数跟某个事件绑定，那么就必须要解绑定。
If you happened to attach the closure to an event, then you would have to detach it from that event.
它在此上下文中用作宏，通过闭包调用函数方法将在定义它的上下文中执行函数调用。
It ACTS like a macro in this context, where calling the method of function via the closure makes the function call in the context of where it's defined.
后续内容还会对闭包与高阶函数做一些有趣的对比。
I'll also circle back to some interesting comparisons between closures and higher-order functions in a later installment.
