Differences from Perl 5

Let's briefly look at some of the changes that happened on the way to Perl 6. In the following sections, you will see a few examples of code in Perl 5 and 6. They are intended for a general understanding of how Perl 5 transforms to Perl 6, but you are not expected to understand every bit of it. All the details about the syntax of Perl 6 will be explained later in this book.
