```python
class FallbackExecutor:
    """
    A class that provides a mechanism for executing tasks with limited error recovery.

    When an exception occurs during task execution, this class attempts to recover by falling back to a default
    action or by trying another method of completing the task. This helps in scenarios where occasional failures
    are expected and need graceful handling.

    Parameters:
        - task_function: Callable function that performs the main task.
        - fallback_function: Callable function that provides an alternative if `task_function` fails.
        - max_retries: int, maximum number of times to retry execution when an exception occurs (default is 3).

    Methods:
        - execute: Attempts to run `task_function`. If it raises an exception and `max_retries` are not exhausted,
                   attempts the `fallback_function`.
    """

        self.task_function = task_function
        self.fallback_function = fallback_function
        self.max_retries = max_retries

    def execute(self) -> None:
        """
        Execute the `task_function` and provide recovery via `fallback_function`.
        """
        retries = 0
        while retries < self.max_retries:
            try:
                self.task_function()
                return
            except Exception as e:
                if retries >= self.max_retries - 1:  # If max retries are reached, raise the last exception
                    raise e
                else:
                    print(f"Task execution failed with error: {e}. Attempting fallback...")
                    self.fallback_function()
                    retries += 1


# Example usage:

def main_task():
    """Main task that might fail"""
    print("Executing main task")
    # Simulate a failure by throwing an exception
    raise ValueError("An unexpected error occurred in the main task.")


def fallback_task():
    """Fallback task to execute if `main_task` fails"""
    print("Falling back to alternative task")


# Create instances of the functions to pass to FallbackExecutor
task_instance = main_task
fallback_instance = fallback_task

# Create a FallbackExecutor instance and use it to handle task execution with error recovery.
executor = FallbackExecutor(task_function=task_instance, fallback_function=fallback_instance)
executor.execute()

print("Task execution completed.")
```

This code snippet defines a `FallbackExecutor` class designed for tasks where occasional errors are expected. The example usage demonstrates how the `execute` method handles task failure by attempting an alternative function defined in the fallback mechanism.
