内容简介从一个Perl爱好者到一个Perl程序员。《IntermediatePerl》将教您如何把Perl作为编程语言来使用，而不仅只是作为一种脚本语言。
Perl是一种灵活多变、功能强大的编程语言，可以应用在从系统管理到网络编程再到数据库操作等很多方面。人们常说Perl让容易的事情变简单、让困难的事情变得可行。《IntermediatePerl》正是关于如何将技能从处理简单任务跃升到胜任困难任务的书籍。
《IntermediatePerl》提供对Perl中级编程优雅而仔细的介绍。由畅销的《学习Perl》作者所著，本书提供了《学习Perl》没有涵盖的内容。
主题包括：
包和命名空间
引用和作用域
操作复杂数据结构
面向对象编程
编写和使用模块
测试Perl代码
为CPAN贡献代码
参照《学习Perl》的成功编排格式，本书的每一章都短小到可以在一到两个小时内读完，并在结束时提供一系列练习题帮助您实践刚刚学到的知识。使用本书，您只需熟悉《学习Perl》的内容并有更进一步学习的决心。
对于不同的人而言Perl是一种不同的语言。对于某些人而言，它只是快速编写脚本的工具，但对于另外的人来说，它就是一种功能完整的面向对象语言。Perl被应用在各种任务当中，从对文本文件进行快速全局替换，到计算需要数星期才能完成处理的海量复杂科学数据。您的使用决定Perl的面貌。但不论您将Perl应用在什么方面，本书将帮助您让应用更加有效、高效和优雅。
《IntermediatePerl》是为了把Perl作为一种编程语言来学习，而不仅是为了写脚本而著。这本书把Perl爱好者变为Perl程序员。
编辑推荐“这是本多么闪耀夺目的Perl书籍啊这本书为那些渴望提高技能或者提升职业生涯的Perl程序员填补了空白。更为重要的是，看这本书有一种向大师学习的感觉。”
