It's been a while since I've been on the net.  I can no longer
access comp.lang.lisp.x from our site, I suppose it went away?

I've just starting playing with XLISP v2.0, particularly the
object-oriented features of it.  I've created new classes with
instance and class variables, and I've used the :new selector
to do so and it works just fine.  However, I see the :isnew
selector in the documentation and I was wondering how that works
compared to :new.

Also, to show my ignorance, I've heard the new Common Lisp standard
includes objects.  How does this compare to objects in XLISP
(unfortunatly I do not know "flavors" or the other object-oriented
variants of LISP).  Is there a good reference on Common Lisp objects
that anyone would recommend?

Thanks,
