Chapter 5. Manipulating Complex Data Structures

Now that you've seen the basics of references, let's look at additional ways to manipulate complex data. We'll start by using the debugger to examine complex data structures and then use Data::Dumper to show the data under programmatic control. Next, you'll learn to store and retrieve complex data easily and quickly using Storable, and finally we'll wrap up with a review of grep and map and see how they apply to complex data.
