Pango attributes are instances of class <gw:wcp> in Guile-Gnome but they are not GOOPS instances (i.e. (instance? x) returns false). Class name <pango-attribute> is not defined at all. How can I test if an arbitrary object belongs to some specific <gw:wcp> class, e.g. if an object is a Pango attribute?
