Does Scala provide a built-in class, utility, syntax, or other mechanism for converting (by wrapping) an Iterator with an Iterable?

For example, I have an Iterator[Foo] and I need an Iterable[Foo], so currently I am:

 val foo1: Iterator[Foo] = ....
 val foo2: Iterable[Foo] = new Iterable[Foo] {
   def elements = foo1
 }

This seems ugly and unnecessary. What's a better way?
