* Scope tests should not forget checking contained names, as they're a public part of the [KaScope] API.
 *
 * Note: Many scopes wouldn't work correctly if the contained name sets were broken, as these names are often the basis for the search.

 *
 * Further modification tracking is implemented with a subscription-based mechanism via [KotlinModificationTopics]. Modification trackers make the most
 * sense when there are many, possibly short-lived objects that need to be notified of a change. In such cases, subscriber management in the
 * message bus adds too much overhead.
