import org.parboiled2._
case class Person(name: String, age: Seq[Int])
//parses "dustin 35 36"
class PersonNumEvaluator(val input: ParserInput) extends Parser {
  def InputLine = rule{ Both ~ EOI }
  def Both = rule { Name ~ Number ~> Person }
  def Name = rule { capture(oneOrMore(CharPredicate.Alpha)) }
  def WS = rule { oneOrMore(" ") }
  def Number = rule { zeroOrMore(WS ~ capture(oneOrMore(CharPredicate.Digit)) ~> (_.toInt)) }
