Overview of this book

Perl is a family of high-level, general-purpose, interpreted, dynamic programming languages consisting of Perl 5 and Perl 6. Perl 6 helps developers write concise and declarative code that is easy to maintain. This book is an end-to-end guide that will help non-Perl developers get to grips with the language and use it to solve real-world problems. Beginning with a brief introduction to Perl 6, the first module in the book will teach you how to write and execute basic programs. The second module delves into language constructs, where you will learn about the built-in data types, variables, operators, modules, subroutines, and so on available in Perl 6. Here the book also delves deeply into data manipulation (for example, strings and text files) and you will learn how to create safe and correct Perl 6 modules. You will learn to create software in Perl by following the Object Oriented Paradigm. The final module explains in detail the incredible concurrency support provided by Perl 6. Here you will also learn about regexes, functional programming, and reactive programming in Perl 6. By the end of the book, with the help of a number of examples that you can follow and immediately run, modify, and use in practice, you will be fully conversant with the benefits of Perl 6.

Using variables

In any programming language, variables are named pieces of memory that you can use to store a value as well as retrieve it. In Perl 6, a variable is a container that can host a value of one of the types, either built-in in the language or created by the user.

Declaring variables

Every variable must be declared before its use in the program. You don't need to declare all the variables at the beginning of the program. From a practical perspective, the point of declaration can (and should) be as close as possible to the place where it is first used. The most practical reason to do that is to make the visibility of the variable better—if you declare too early, you force the reader of your program to...
