With the NILs we run into a problem, because a property value of NIL means that this property does not exist. So it can never be extracted from the object itself. To cover non-NIL properties, you could do (mapcar '((X) (or (pair X) (cons T X))) (getl Tst) ) > Is there some other function/mechanism I could use instead? Hmm, not that I can think of at the moment. To solve the problem with the NILs, you'll have to keep a separate record of possible properties (as is done, for example, in the '+Entity' objects).
