Hi, guys, I generated a CLOS extension over lambda-gtk. Here are details http://borigen.narod.ru/gtk-on-clos/ I rewrote the original examples with CLOS and added a couple of others. I really interested in what you, guys, think about this. Any comments and suggestions are very welcome. I also have a plan to document and post the functions which generates this CLOS extensions, since currently, I generated only those classes needed for proper functioning of the examples. D.
