I don't understand what you mean when you say "locals are not hierarchical". Locales are just name spaces. Locales are implicitly referenced through path (18!:2). The path determines how locales are searched to resolve a name not found in the current locale. This search is hierarchical. The locales are searched in the order specified in 18!:2. But each locale has its own path. In this way the hierarchy of locales depends on the current locale. In this way it is easy to implement classes in J. But paths can be used outside of J classes in interesting ways.
