Gain the skills to begin developing Perl 6 applications from the ground up in this hands-on compact book, which includes a foreword from Larry Wall, creator of Perl. You’ll learn enough to get started building with Perl 6, using Perl 6’s gradual typing, handy object orientation features, powerful parsing capabilities, and human-usable concurrency. After a short introduction, each chapter develops a small example project, explaining the Perl 6 features used. When the example is done, you’ll explore another aspect, such as optimizing further for readability or testing the code. 
Along the way you’ll see Perl 6 basics, such as variables and scoping; subroutines; classes and objects; regexes; and code testing. When you’ve mastered the basics, Perl 6 Fundamentals moves onto more advanced topics to give you a deeper understanding of the language. You’ll learn, amongst other things, how to work with persistent storage, how to generate good error messages, and how to write tricky applications such as a file and directory usage graph and a Unicode search tool.
