Programming Tips - What does a "return" in a "match" do?

Date: 2013jan4 Language: Scala Q. What does a "return" in a "match" do? A. This surprised me. I thought => was a function call so a return would just end the function and control would continue after the match. But a return in a match exits the containing function - which is called "test()" in this example:
def test() { var a = "hello" System.out.println("start of test()") a match { case "one" => System.out.println("got one") case "two" => System.out.println("got two") case "hello" => { System.out.println("got hello"); return; } case _ => System.out.println("got default") } System.out.println("end of test()") }
