Auf die gleiche Weise können Sie `finally` verwenden, um sicherzustellen, dass die Exit-Schritte ausgeführt werden, unabhängig davon, ob eine Exception geworfen wurde oder nicht.

In the same way, you can use `finally` to make sure the exit steps are executed, no matter if there was an exception or not.

## Sub-dependencies with `yield`

You can have sub-dependencies and "trees" of sub-dependencies of any size and shape, and any or all of them can use `yield`.
