That does work indeed. I know understand that make-class does not accept initforms at all. Shouldn't my make-class call above fail then as I give a list rather than just a symbol? Thanks for looking into it!
Note: See
TracTickets for help on using
tickets.
Try
...(make-class (<standard-class>) (bar))...
