Note that we switch to using curly braces, indicating a function block rather than parameters, and the function is a case statement. This means that the function block we pass to flatMap is a partialFunction that is only invoked for items that match the case statement, and in the case statement the unapply method on tuple is called to extract how to add lost space to drive c This is an excerpt from the Scala Cookbook (partially modified for the internet).

- One difference between Scala and Java is that whereas Java requires you to put a public class in a file named after the class—for example, you'd put class SpeedRacer in file SpeedRacer.java —in Scala, you can name .scala files anything you want, no matter what Scala classes or code you put in them.
