在我决定用脚本语言取代它之前，我必须将它添加到旧的数据驱动规则引擎中。

注意上面代码中的bug;我只是证明了它是正确的，并没有尝试过。

这是唐纳德·克努斯写的。

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;
}
