A little bit late to the party, but ENUM is a very good and clean practice. Lets say a user chooses an option from a ComboBox. Then in other places of your code you want to make decisions or execute action based on the choice of the user. It's a very clean way to use ENUM's for this, since you're always talking in the same way. Besides that you could easily add more area's to your script without modifying much code.
