I concur (Thien-Thi’s message shows how this can be achieved.) So it’s a matter of extending Emacsy’s ‘define-interactive’ to add an object property. Then you could have a ‘fold-commands’ procedure that traverses all the bindings of all the available modules (or a subset thereof), and iterates on those that match ‘command?’. Ludo’.
