Could you give some concrete examples of things you'd (be able to) do with it? Given that we start with (signal ERROR-SYMBOL ERROR-DATA) and the "other end point" of an error is the `condition-case` variable bound to a value of the form (ERROR-SYMBOL . ERROR-DATA), I find it a bit hard to see how we could usefully use "objects" somewhere in-between, but maybe some examples can help me out of the rut. Stefan
