Labelled Multiple Returns

A cool idea I found at http://stackoverflow.com/questions/1827672/is-there-a-way-to-have-tuples-with-named-fields-in-scala-similar-to-anonymous-cl. A very simple idea but very useful.
To summarize, you want to return multiple values but want to assign names to the values rather than use a tuple which more or less assigns indices to the different values. Here are a couple of solutions:

Using structured types. Simplest solution with the least extra code.

1. scala> def multipleReturns1 = {
2.      | new { val first = 1; val second = 2 }
3.      | }
4. multipleReturns1: java.lang.Object{def first: Int; def second: Int}
6. scala> multipleReturns1
7. res0: java.lang.Object{def first: Int; def second: Int} = $anon$1@549b6976
9. scala> res0.first
10. res1: Int = 1
12. scala> res0.second
13. res2: Int = 2
15. scala> import res0._
16. import res0._
18. scala> first
19. res3: Int = 1
21. scala> second
22. res4: Int = 2

Using case classes. Returns a product which has properties that may be useful.

1. scala> def moreReturns = {
2.      | case class Returns (one:Int, two:Int)
3.      | Returns(1,2)
4.      | }
5. moreReturns: java.lang.Object with ScalaObject with Product{def one: Int; def two: Int}
7. scala> moreReturns
8. res5: java.lang.Object with ScalaObject with Product{def one: Int; def two: Int} = Returns(1,2)
10. scala> res5.one
11. res6: Int = 1
13. scala> res5.two
14. res7: Int = 2
16. scala> import res5._
17. import res5._
19. scala> one
20. res8: Int = 1
22. scala> two
23. res9: Int = 2
25. scala> res5.productIterator foreach println _
26. 1
27. 2
29. scala> res5.productPrefix
30. res15: java.lang.String = Returns
