What are best practices for working with overloading operators?

When working with operator overloading in Perl, it's essential to follow best practices to ensure your code remains clean, understandable, and maintainable. Below are some key points to keep in mind:

• Keep it intuitive: Overloaded operators should behave in a way that users would expect. For instance, overloading "+" for an object representing a number should perform addition.
• Document behavior: Clearly document how each operator has been overloaded, especially if the behavior differs from standard usage.
• Maintain performance: Be cautious of performance implications when overloading operators, as it might affect the efficiency of your code.
• Implement multiple operators: If you overload one operator, consider overloading related ones (like "+", "-", and "=") to provide a full experience.
• Avoid complexity: Keep the overloaded logic as simple as possible. Complex behavior can confuse users and lead to maintenance challenges.

Following these best practices will help in creating robust and user-friendly Perl applications that utilize operator overloading effectively.
