What are best practices for working with Core vs non-core modules?

When working with Perl, distinguishing between core and non-core modules is vital for maintaining efficient and manageable code. Here are some best practices to consider:

• Understand Core Modules: Familiarize yourself with the core modules that come bundled with Perl. These modules are generally well-documented, maintained, and more stable.
• Use Non-Core Modules Judiciously: Non-core modules can provide specific functionalities not included in core. However, evaluate their popularity, maintenance status, and compatibility with your version of Perl.
• Consider Dependencies: Keep an eye on the dependencies introduced by non-core modules. Too many dependencies can complicate deployment and increase the risk of conflicts.
• Version Control: Maintain version control for non-core modules to ensure consistency across different environments, especially if using CPAN.
• Performance Profiling: Test the performance of both core and non-core modules in your application to identify the best options for your specific use case.
• Documentation and Community Support: Utilize modules with comprehensive documentation and good community support. This can save you time and effort when troubleshooting issues.
