Refactoring legacy Perl code to modern best practices involves applying the v5.36 pragma to enable strict, warnings, and subroutine signatures by default. This process eliminates outdated boilerplate and replaces insecure patterns like two-argument open calls with safe three-argument alternatives.

Type-safe object-oriented programming in Perl is best achieved using Moo. This lightweight framework reduces boilerplate while providing robust type constraints and modern object patterns, making your Perl application architecture more maintainable and approachable for new contributors.

Secure file I/O operations in Perl 5.36 are handled using Path::Tiny. This modern module eliminates security risks associated with legacy two-argument open calls by providing safe, copy-paste ready patterns for robust file reading and writing.

Modern Perl error handling with Try::Tiny provides a robust try-catch mechanism to safely catch and manage exceptions. This replaces legacy eval-based error handling patterns, reducing debugging friction and making your Perl 5.36 codebase more reliable.

Named captures in Perl regex significantly improve code readability by assigning explicit names to matched patterns. Modern Perl 5.36 idiomatic patterns provide copy-paste ready examples for using named captures to make complex regular expressions easier to maintain and debug.

Moo is limited to lightweight object-oriented programming in Perl, intentionally avoiding the full meta-protocol complexity of Moose. For applications requiring extensive runtime class introspection or advanced meta-level manipulation, Moo may not provide sufficient capabilities.
