Refactor legacy Perl scripts by converting them to modern idiomatic Perl 5.36 patterns, enabling strictness and warnings via the `v5.36` pragma, and applying subroutine signatures to reduce argument bugs and improve readability.

The best way to add subroutine signatures is by adopting the `v5.36` version pragma, which enables signature-friendly subroutines by default, allowing you to define clear function interfaces with defaults and slurpy params for self-documenting code.

Postfix dereferencing improves Perl code maintainability by providing a more readable syntax for accessing complex data structures, replacing legacy dereferencing patterns with clearer, safer data access methods that are easier to reason about under real-world change.

Yes, you can use modern `try/catch` error handling or `Try::Tiny` when modernizing Perl modules, applying robust exception handling patterns that make regressions easier to catch with tests during refactoring tasks.

Yes, Perl 5.36 replaces separate `use strict` and `use warnings` declarations by serving as a single entry point pragma that enables both strictness and warnings by default, streamlining module organization conventions.

A limitation of refactoring Perl code to version 5.36 idioms is that it requires a Perl runtime supporting the 5.36+ feature set, meaning older production environments may need an interpreter upgrade before the modernized scripts can execute.
