protocol BidirectionalCollection<Element> : Collection where Self.Indices : BidirectionalCollection, Self.SubSequence : BidirectionalCollectionA collection that supports backward as well as forward traversal.
protocol RangeReplaceableCollection<Element> : Collection where Self.SubSequence : RangeReplaceableCollectionA collection that supports replacement of an arbitrary subrange of elements with the elements of another collection.
