    print(f"An error occurred: {e}")


# Output:
# Executing main function.
# An error occurred: unexpected failure (this part is just a placeholder for demonstration purposes)
```

This example includes an `execute` method that attempts to run the primary function. If an exception occurs, it tries each fallback in turn until one succeeds or all are exhausted. The `error_handler` allows for custom handling of exceptions if no fallback succeeds.
