protocol LazySequenceProtocol : SequenceA sequence on which normally-eager sequence operations are implemented lazily.
associatedtype Element where Self.Element == Self.Iterator.ElementA type representing the sequence’s elements.
struct ExclusiveReductionsSequence<Base, Result> where Base : SequenceA sequence of applying a transform to the element of a sequence and the previously transformed result.
associatedtype Elements : Sequence = Self where Self.Element == Self.Elements.ElementA Sequence that can contain the same elements as this one, possibly with a simpler type.

func reductions<Result>(_ initial: Result, _ transform: @escaping (Result, Element) -> Result) -> ExclusiveReductionsSequence<Elements, Result> Returns a sequence containing the accumulated results of combining the elements of the sequence using the given closure.
func reductions<Result>(into initial: Result, _ transform: @escaping (inout Result, Element) -> Void) -> ExclusiveReductionsSequence<Elements, Result> Returns a sequence containing the accumulated results of combining the elements of the sequence using the given closure.
func split(maxSplits: Int = Int.max, omittingEmptySubsequences: Bool = true, whereSeparator isSeparator: @escaping (Element) -> Bool) -> SplitSequence<Elements> Lazily returns the longest possible subsequences of the sequence, in order, that don’t contain elements satisfying the given predicate.
func uniqued<Subject>(on projection: @escaping (Element) -> Subject) -> UniquedSequence<Self, Subject> where Subject : Hashable Returns a lazy sequence with the unique elements of this sequence (as determined by the given projection), in the order of the first occurrence of each unique element.
