// Idiomatic solution using extrators
// Extractors allow us to bind parameters to an object and are usable in pattern matches to see if a pattern can apply to the params submitted. 
// Note this is simialr to case classes, but works against an Object (which are like 'static' classes in Java). Also it incurs some performance penalties
// as opposed to using case classes
class BowlingForExtractors() {

    def score(bowls:List[Int]) = scoreFrames(bowls).slice(0,10).sum    // take the first 10 elements from the List and sum them..any additional elements are the result of additional strikes

    def scoreFrames(bowls:List[Int]) : List[Int] = bowls match {
        case Nil => List(0)
