OK. I think you are right. To the vendor: The Case for :default-initargs ------------------------------- Wow. Just checked the source of the CliniSys system, which includes a homebrewed GUI--looks like over two hundred occurrences of "default-initargs". Don't know how many slots were addressed by each :d-i. Why so many? Sometimes when I subclass I want to tailor it by supplying a specific form for some slot defined in a superclass (direct or indirect). With Corman Lisp as it stands, I have to restate the slot so I can supply the tailoring form as the initform of the slot. Not good. And now if I want to modify that slot definition...etc etc. I get into this a lot because Cells promote object reuse. I can get custom behavior out of a relatively generic class by supplying custom rules for a core set of generic slots. I /could/ bypass the :d-i mechanism and make functions such as make-instance-of-oddball in which custom initargs were supplied to make-instance, but then it's not CLOS anymore. -- kenny tilton clinisys, inc http://www.tilton-technology.com/ --------------------------------------------------------------- "Cells let us walk, talk, think, make love and realize the bath water is cold." -- Lorraine Lee Cudmore ------------------------ Yahoo!
