我在重用我很久以前写的一个PHP类时发现了这一点。我仍然不记得那里有什么，我仍然发现它没有任何用处……我甚至不记得我写过那篇评论;所以当我找到它的时候，我真的笑出声来了。

try
{               
    // Some database logic
}
catch (Exception $ex)
{
    // sure, it looks silly and I honestly cant remember what code used to go here... but i swear i will
    // find a use for this code.... eventually....
    throw $ex;
}

//marco 2007.1.23
//I didn't do it

不是注释，而是属性

还有一个是我在IHttpHandler的实现中看到的

//What is this?
public bool IsReusable
{
    get{return false;}
}

/* My lawyer told me not to reveal */

// Okay, let's do the loop, yeah come on baby let's do the loop
// and it goes like this ...

我经常看到这种情况:

// TODO make this work
