If you look through my examples you will find symbolic references being used as well. Turning around a recent discussion between us, this is the same issue as using AUTOLOAD all over. Using it immediately opens you up to all sorts of confusions and possible kinds of grief. But with it you can effectively write a program that writes your code for you - which can accomplish very powerful things. Therefore use it, with caution, wisely, but only where it makes sense.

In other words all rules are there because most of the time they make your life easier. But they have exceptions, and when you arrive at a legitimate exception, you should not fear unnecessarily to break the rule. However if you find yourself often deciding that the rule is to be broken, then you are probably doing something seriously wrong and you are probably mistaken. (Because, after all, most of time the rule is right!)
