In this chapter, we learned about working with exceptions in Perl 6. We examined in detail ways to throw, catch, and hide exceptions by using different mechanisms of the language—try blocks and CATCH phasers. We talked about soft failures, which are postponed exceptions that are only thrown when it is really unavoidable. Also, we demonstrated how to use the object-oriented approach to handle exceptions of different types and how to create a custom exception.

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.
