If you still don't get what all the fuss is about with functional programming, look no further than JodaTime Date/Calendar is clearly an imperative design. Mutable, ugly, non-thread-safe, and widely despised JodaTime, on the other hand, is very obviously designed in a functional style. Immutable objects, thread safe, calculations performed my mapping one type to another (i.e. You can't take a DateTime and change the day of month it represents, instead you add a specified number of days to yield a new DateTime instance) It's almost universally recognised as being clean, elegant, and a pleasure to use now imagine you could write entire programs like that...
