I would like to make a general point about PopLog and Pop-11 verses Common Lisp. Pop-11 does have some advantages as a language, and I don't want to imply that it doesn't. But in many cases where Pop-11 or PopLog has some nice feature that isn't in Common Lisp it's worth remembering that it's much easier to add lots of nice things if you are doing it for one (or even for several) implementation rather than for a language that a number of different people will implement. This is also why several Common Lisp implementations have stack groups, light-weight processes, and weak pointers even though Common Lisp doesn't. -- jd
