我曾经参与过Windows 3.0的源代码。(我赶紧补充一句，作为一名微软员工，不是!)在那里，我遇到了一个文件加载器，它可以多次重新输入，并且有一个讨厌的双关语的例子(只是为了显示作者有多聪明)。

这些乱七八糟的可重入代码是用Intel程序集jmp指令(在C代码中间)执行的，它的标签是“we_are_not_in_kansas_any_more_toto”。

Don't use the fucking BindCompany method!!!"); } // P.S. this method is a joke ... the rest of the class is fucking serious } /// <summary> /// This returns true if this control is supposed to be doing anything /// at all for this request.

更新:代码的原作者已经暴露了自己，所以我必须在适当的地方给予赞扬。Dan McKinley在我入职后不久就离开了我所在的公司，他讲述了更多关于代码的内容，解释了一些背景知识和“Richard”所写的一些“WTF”。

// set break point here - you'll never reach it

后面是四个嵌套的for循环
