Advantages to the table lookup code:

1. Identifies which functions have a given use with less work than writing a separate package.
2. Opens you up for refactoring your code later by dynamically creating closures.
3. If you need to later, you can choose to modify the contents of the table hash dynamically without running the risk of namespace conflicts.

And yes, I have gained every one of these benefits from table-driven code. I also know how to do much the same things with typeglobs - but find the hash approach cleaner. I admit that is subjective.

And details like that are nothing compared to the crap variable and function names. I mean, conservation is good and all, but a few more letters wouldn't hurt, would it?
