通过使用 sys_nerr全局变量和strerror()函数，将可以很轻松地快速编写一些代码（请参见清单5）以打印出系统的所有内置错误消息。
Using the sys_nerr global variable and the strerror() function, you can easily whip up some code (see Listing 5) to print out all of the built-in error messages of the system.

We discussed how template inheritance can be used to add behaviors (like starting and committing a global transaction) transparently to the servlet code.
调用Web服务时，运行代码来以恰当的值初始化所有全局枚举对象（在本例中是创建一个BookTypeInitializer类的实例来完成的）。
When the Web service is called, run code to initialize all the global enumeration objects with proper values (in our case, by creating an instance of the BookTypeInitializer class).

历史应用程序(即很过时的遗留代码)有时会直接引用这些全局变量，但会在编译过程中产生错误，因为它们的声明并不一致。
Historical applications (that is, horribly outdated legacy code) sometimes refer to these directly, but produce errors during compilation because they're declared inconsistently.
最终，为了避免破坏代码的可读性ThoughtWorks的工程通常避免使用编程语言特有的语法(例如Ruby语言中匿名全局变量)。
To this end, ThoughtWorks projects generally avoid the more magical features of languages (like the implicit global variables in Ruby, for example) because it hurts readability.
这可以通过在信号处理程序代码中设置一个全局标志并在完成关键部分的代码之后检查这个标志来实现。
