`yield` の前の前半は、アプリケーションが開始される「前」に実行されます。

`yield` の後半は、アプリケーションの処理が「終了」した「後」に実行されます。

### 非同期コンテキストマネージャ { #async-context-manager }

この関数には `@asynccontextmanager` がデコレートされています。

これにより、この関数は「非同期コンテキストマネージャ」になります。

- we also seem to have artifact information tangled inside the plugin model
- we have to deal with scripting implementations (groovy, beanshell, ruby)
- we need to deal with a shared context for plugins, like the guarded mojos
- we need to deal with plugins as core application logic which can also interact with plugins

* Along with this comes the testing strategies that make this work
