This is more or less what we did in binarycloud. We've created the notion of
packages and somewhat of a hierarchical namespace in userland. It works really
well, although the usefulness would probably be lost on small applications or
scriptlets. Other than possibly making import into a language construct as
opposed to a function, and having the the engine do the package management,
which is more convenience than anything else, we haven't found much reason to
implement this in the language.
