What are best practices for working with source filters?

Working with source filters in Perl can be powerful but comes with certain complexities. Here are some best practices to keep in mind:

• Limit Usage: Use source filters sparingly. They can make your code difficult to read and maintain.
• Documentation: Clearly document your use of source filters to help other developers understand the transformations applied to the code.
• Testing: Thoroughly test your code with the source filters applied to ensure that it behaves as expected.
• Namespace Usage: Consider keeping your source filter in a dedicated namespace to minimize the risk of confusion in larger projects.
• Fallback Options: Provide alternatives or fallbacks if the source filter can't be applied, ensuring that the code doesn't break in its absence.
