And all of them can use `yield`.

In this case `dependency_c`, to execute its exit code, needs the value from `dependency_b` (here named `dep_b`) to still be available.

And, in turn, `dependency_b` needs the value from `dependency_a` (here named `dep_a`) to be available for its exit code.

In the previous example, because the classes were different, we had to use the `response_model` parameter. But that also means that we don't get the support from the editor and tools checking the function return type.

But in most of the cases where we need to do something like this, we want the model just to **filter/remove** some of the data as in this example.

Existing object replication as detailed [here](https://aws.amazon.com/blogs/storage/replicating-existing-objects-between-s3-buckets/) can be enabled by passing `existing-objects` as a value to `--replicate` flag while adding or editing a replication rule.
