well other collection use map. example:

scala> val ls = list(1,2,3).toiterator ls: iterator[int] = non-empty iterator  scala> ls.map(_.tostring) //it map(x+""). see comments on why bad res0: iterator[string] = non-empty iterator  scala> res0.next res1: string = 1  scala> res0.next res2: string = 2  scala> res0.next res3: string = 3
