Remove duplicates from list in scala (but use better `list.distinct`)

dedupe.scala

object ListUtil {
	def dedupe[T](elements:List[T]):List[T] = elements match {
		case Nil => elements
		case head::tail => head :: dedupe(tail filterNot (_==head))
	}
}


import ListUtil._

println( dedupe(List("one","two","one")) )  // List(one, two)
println( dedupe(List(1,2,3,4,5,2,3,6,1,1)) ) // List(1, 2, 3, 4, 5, 6)
