I think there was, in fact, some preliminary implementation of NIL, but
it wasn't completed and the effort was abandoned. I don't believe it
played any part in subsequent developments, e.g. NVT. Jeff Rulifson and
Bill Duvall were the key people behind NIL; they're still around and
could be tracked down. Jeff was at Sun the last time I saw him.
