```

This code defines a `FallbackExecutor` class that attempts to execute a series of callables in order until one succeeds or all fail. If all executors fail, it uses an error handler function to provide a fallback result. The example usage demonstrates how to use this class with simple arithmetic functions and a default fallback value.
