class FallbackExecutor:
    """
    A class for executing tasks with fallback options in case of errors.

    This implementation allows defining multiple execution strategies and automatically
    attempts each one until a successful execution is achieved or all fall back options are exhausted.
    
    Args:
        exec_strategies (list[Callable]): A list of functions that accept the same arguments and return the same type.
        fallback_strategy (Optional[Callable], optional): The function to execute if none of the provided strategies succeed. Defaults to None.

    Returns:
        The result returned by the first successful execution strategy or, if all fail, the result of fallback_strategy.

    Raises:
        Exception: If no successful execution is achieved and a fallback strategy is not defined.
