    A class for executing tasks with a fallback mechanism in case of errors.
    
    This implementation allows specifying multiple handlers to be tried
    in sequence until one succeeds or all fail.

    Args:
        *handlers (Callable): Variable number of function handlers. Each handler should accept the same arguments as the main task.
    """

        Execute the main task or one of its fallbacks.

        Args:
            main_task (Callable): The primary function to be executed.
            *args: Positional arguments to pass to both the main task and fallback handlers.
            **kwargs: Keyword arguments to pass to both the main task and fallback handlers.

        Returns:
            bool: True if at least one of the functions completes successfully, False otherwise.
