Perl 6 Deep Dive

By: Andrew Shitov

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.

Working with Operators

Operators are the elements of the syntax of the language which perform actions over their operands and return a result. Perl 6 is a language with dozens of operators. Some of them are inherited from Perl 5 (directly or with modifications), some were invented especially for Perl 6. On top of the set of regular operators, Perl 6 defines the so-called meta-operators and hyper-operators, which extend the meaning of regular operators for working on a group of values.

In this chapter, we will cover the following topics:

  • Operator classification
  • Unary operators
  • Binary operators
  • Ternary operator
  • Bitwise operators
  • Miscellaneous operators
  • Operator precedence
  • Substitution meta-operators
  • Assignment meta-operators
  • Negation meta-operators
  • Reversed meta-operators
  • Creating hyper-operators
  • Types of hyper-operations
  • Reduction hyper-operators
  • Cross hyper-operators
  • Zip hyper...
