What are best practices for working with closures?

Working with closures in Perl can greatly enhance your code's flexibility and maintainability. Here are some best practices to follow:

  • Keep it simple: Write clear and concise closure functions to avoid complications.
  • Limit scope: Restrict the visibility of variables used in closures to prevent unintended side effects.
  • Use lexical variables: Use 'my' to declare variables that are accessible only within the closure.
  • Avoid global state: Minimize reliance on global variables to keep your closures predictable.
  • Document usage: Clearly document the purpose and usage of closures within your codebase.
