perl-patterns

Idiomatic Perl 5.36+ patterns and best practices for building robust, maintainable applications. 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. A single use v5.36 replaces the old boilerplate and enables strict, warnings, and subroutine signatures. Use signatures for clarity and automatic arity checking. Understand scalar vs list context — a core Perl concept. Use postfix dereference syntax for readability with nested structures. Infix type-check — replaces blessed($o) && $o->isa('X') .
