Scala Collection framework

I'm really impressed by the elegance of the collection operations of Scala. For example the following code

       val l = List(1,2,3)
        val (l1, l2) = l partition (_>1)
        println("l1 = " + l1)
        println("l2 = " + l2)

will produce:
l1 = List(2, 3)
l2 = List(1)

We can also do that with one line of code:
val (l1, l2)  = List(1,2,3) partition (_>1)

Beautyfull !
