I have a Scala List, how can I get a TraversableOnce?

Question

Starting with a Scala list. ``` val list = List(1,2,3,4) ``` How can I convert it to a TraversableOnce?

Accepted Answer

You already have one, since `List[A]` is a subtype of `TraversableOnce[A]`. You should not need to do anything to convert it. To verify this: ``` scala> implicitly[List[Int] <:< TraversableOnce[Int]] res0: <:<[List[Int],TraversableOnce[Int]] = ```
