the number of items in the channel corresponds to the number of active uses,
the capacity of the channel corresponds to the maximum number of simultaneous uses,
sending an item acquires the semaphore, and receiving an item releases
the semaphore.
This is a common idiom for limiting concurrency.

Note that, much like [dependencies in *path operation decorators*](dependencies/dependencies-in-path-operation-decorators.md), no value will be passed to your *path operation function*.

The end result is that the item paths are now:

...as we intended.

* They will be marked with a list of tags that contain a single string `"items"`.
