What are best practices for working with filehandles (lexical)?

When working with filehandles in Perl, especially lexical filehandles, there are several best practices to ensure your code is clean, efficient, and free of potential issues. Here are some recommended practices:

• Use lexical filehandles: Always prefer lexical filehandles over global ones as they are limited in scope and less error-prone.
• Close filehandles: Make sure to always close your filehandles when you're done using them to free resources.
• Error handling: Always check for errors when opening files and handle them appropriately.
• Use 'use strict' and 'use warnings': This helps catch potential issues in your code before running it.
• Maintain readability: Keep your code clean and organized to make it easier to read and maintain.

By following these practices, you can ensure that your file handling in Perl is robust and less prone to bugs.
