The following trick is of great use in writing window-based applications in Medley. I find it makes il:windowprop (and the very notion of window properties) much more useful in the brave new world of Xerox Common Lisp. Simply make the following declaration: (defsetf il:windowprop il:windowprop) and you'll be able to use such handy idioms as (setf (il:windowprop window 'prop) ...) ; saves on clarity, not typing (push ... (il:windowprop window 'prop)) (pushnew ... (il:windowprop window 'prop)) (pop (il:windowprop window 'prop)) (incf (il:windowprop window 'prop)) and their friends. Herb
