The core of objects.fs works without any vocabularies, so I guess it
does not rely on "vocabulary sealing", whatever that may be.  There is
a bit of wordlist stuff for allowing the same name for (different)
instance variables of different classes, though; that's because the
classic prefix approach for avoiding name collisions does not work
well with inheritance.
