# Modern Perl Development Patterns Idiomatic Perl 5.36+ patterns and best practices for building robust, maintainable applications. ## When to Activate - Writing new Perl code or modules - Reviewing Perl code for idiom compliance - Refactoring legacy Perl to modern standards - Designing Perl module architecture - Migrating pre-5.36 code to modern Perl ## How It Works Apply these patterns as a bias toward modern Perl 5.36+ defaults: signatures, explicit modules, focused error handling, and testable boundaries. The examples below are meant to be copied as starting points, then tightened for the actual app, dependency stack, and deployment model in front of you. ## Core Principles ### 1. Use `v5.36` Pragma A single `use v5.36` replaces the old boilerplate and enables strict, warnings, and subroutine signatures. ```perl # Good: Modern preamble use v5.36; sub greet($name) { say "Hello, $name!"; } # Bad: Legacy boilerplate use strict; use warnings; use feature 'say', 'signatures'; no warnings 'experimental::signatures'; sub greet { my ($name) = @_; say "Hello, $name!"; } ``` ### 2. Subroutine Signatures Use signatures for clarity and automatic arity checking. ```perl use v5.36; # Good: S
