Advantages of inheritance(Level 4)

[theodoreleebrant]

What is the inherent advantage of using inheritance instead of, let's say, enums for the type of tasks in Level 4? As I see it, using inheritance introduces certain inflexibilities (e.g. having a need to add new classes to create any further type of task) as compared to enums. Additionally, enums might have some advantages in pattern-matching (although Java being Java...)

Actually now that I think again about it, they might have differing behaviours in the future...
