难道你从没写过测试用例么？）。
一个写得好的测试用例应该是任何一个
Perl
用户
都能运行并重现你所找到的问题的。有了能清楚重现
bug
的测试用例后，可以通过
GitHub
链接
https://github.com/Perl/perl5/issues
提交问题。
如果一切顺利，
bug
报告发送后不出几分钟，你就会收到来自开发团队的回应。如果
问题已经解决，他们会给你发送一个补丁文件，然后你可以自己打上补丁，继续手头

Perl
程序。
Perl
不需要特殊的

言权，无法向你推荐（相反，我们倒是有一堆理由可以说明根本没必要用这类商业软
件）。不过，你自己的开发环境归根结底还是你自己说了算。随便问三个程序员他们
用什么开发环境写程序，或许会得到八种不同答案。
一般来说，你应该使用程序员专用的文本编辑器，而不是普通的编辑软件。两者有什
么不同呢？程序员专用的文本编辑器可以快速方便地执行写程序时常用的那些操作，
比如调整一段代码的缩排，或是查找并定位成对的括号。 ...
