struct JoinedByCollection<Base, Separator> where Base : Collection, Separator : Collection, Base.Element : Collection, Separator.Element == Base.Element.ElementA collection that presents the elements of a base collection of collections concatenated using a given separator.
struct Indexprotocol BidirectionalCollection<Element> : Collection where Self.Indices : BidirectionalCollection, Self.SubSequence : BidirectionalCollectionA collection that supports backward as well as forward traversal.
