This code provides a basic example of how to implement and use the `FallbackExecutor` class. It includes a primary function that could potentially raise an exception during execution, and fallback functions defined for specific exceptions like `ZeroDivisionError`. The `general_exception_handler` serves as a default catch-all if no other suitable fallback is available.
