最初的《毁灭战士》拥有一个带有静态墙壁的引擎，但却不能移动;结果，所有的门都是垂直打开的;任何东西都不可能水平移动。当源代码发布后，我在查看代码时，在处理门的源文件中看到了这个，在一大块注释掉的代码的开头:

// UNUSED
// Separate into p_slidoor.c?

#if 0           // ABANDONED TO THE MISTS OF TIME!!!
//
// EV_SlidingDoor : slide a door horizontally
// (animate midtexture, then set noblocking line)
//

我刚刚完成了一个日志框架(使用Trace，为什么没有这样的存在我不知道)。我做了一个继承自TraceListener的方便基类。它覆盖了所有的TraceListener方法，并将它们路由到一个方法中——因此有很多文档注释:

// TODO: Need some codemonkey to doc comment this class.

事实上，有一天我在一些代码上看到了这个，这些代码是在截止日期很急的时候写的。

//This was clearly written under duress
