Okay. So is your submodule design not intended to address the "I want to encapsulate implementation details so they're only visible to several units of code in different files, but not the entire module" use case? Because if there's no way to scope a symbol to "everything inside this submodule, but nothing outside this submodule", I think it leaves that use case unserved.
