func next() -> members? }

var items = [10,20,30].generate() while let x = items.next() { println(x) }

for lists in map([1,2,3], {i in i*5}) { println(lists) }

println([100,200,300]) println(map([1,2,3], {i in i*10})) When we run the above program using playground, we get the following result: 10 20 30 5 10 15 [100, 200, 300] [10, 20, 30]
