You get an exception if you try to access them.

There would be no "ls -la".
Objects would be put into container objects. Of course, it might
be desirable to have some containers that index things by name
like a UNIX file system. In that case, if you had a container of
documents called "foo", you might do something like....
(names foo) =>
("doc1", "doc2", "doc3", "doc4")
and to access a document by name...
(find-by-name foo "doc1") =>
("a document about Lisp OS....")
