BoxLang has always been an extensible language. As of 1.17.0, it is a hierarchically extensible one. Modules can now contain other modules; aka Module Inception. Recursively. To any depth. Each nested module gets its own class loader, chained to its parent's, and BoxLang's own ModuleService discovers, registers, activates, and unloads that entire tree itself. No package manager. No build tool. No install ordering. Drop in one artifact and everything it depends on comes with it, already wired up and already isolated. Not only that, you can now package modules into a single jar.
