In this chapter, you'll see some alternative ways to write Perl code. For the most part, these techniques don't make the language more powerful, but they make it easier or more convenient to get the job done. You don't have to use these techniques in your own code, but don't skip this chapter. You're certain to see these control structures in other people's code, sooner or later. In fact, you'll see these things in use by the time you finish reading this book.
