What are some common challenges Perl programmers face when maintaining legacy codebases?

Perl Programmers often encounter challenges when working with legacy code, such as deciphering undocumented scripts, ensuring compatibility with newer systems, and refactoring code for improved readability and performance. Since Perl has a flexible syntax, older code may vary significantly in style and structure, making it harder to debug or enhance. Collaborating with team members and following consistent coding standards can help address these issues and streamline ongoing maintenance.
