Sequence wildcards and sequence arguments in Scala

	import scala.collection.immutable.Queue

	val q = Queue(1, 2, 3)

	// When pattern matching against a sequence, the sequence wildcard _*
	// can be used as the last pattern and will match an arbitrary number of
	// elements. To bind the matched sequence to a variable, use the form
	// `x @ _*`:
	val restSeq = q match { case Queue(x, xs @ _*) => xs }
	// --> rest: Seq[Int] = Queue(2, 3)
