perl-patterns

The perl-patterns skill provides developers with a comprehensive guide to modern Perl 5.36+ programming practices. It focuses on idiomatic patterns, best practices, and conventions designed to produce robust and maintainable Perl applications. By standardizing approaches to common programming tasks, such as subroutine signatures, context sensitivity, and structured error handling, this skill helps developers write code that is more predictable, testable, and aligned with the latest Perl features.

This skill emphasizes practical features for everyday Perl development. Key capabilities include leveraging the `v5.36` pragma for simplified boilerplate, using subroutine signatures for clarity and automatic arity checking, applying postfix dereferencing for improved readability of nested data structures, and employing modern type-checking with the `isa` operator. It also provides guidance on structured error handling using patterns such as `eval/die`, `Try::Tiny`, and native `try/catch` in Perl 5.40+, as well as recommendations for object-oriented programming using Moo for lightweight class design. The skill is intended to help developers transition legacy code to modern standards and write new code that adheres to contemporary Perl idioms.

Target users include Perl developers maintaining or modernizing existing applications, developers writing new Perl modules, code reviewers, and architects designing module structures or migrating pre-5.36 code to current standards. It is particularly useful for those seeking to improve code clarity, enforce consistency across projects, and adopt modern Perl features to reduce boilerplate and potential errors. Common use cases include code refactoring, module design, idiomatic code reviews, and building scalable, maintainable applications with modern Perl patterns.
