Proposal: Array's fullfill function

[wongzigii]

func fullfill(element: Any, count: Int) {
}

let a = [1, 2, 3, 4]
a.fullfill(0, 2) // [1, 2, 3, 4, 0, 0]

fullfill will extend the array with several numbers of elements.

So this function just appends the element, n times towards the end of the array?
