The tricky part is a CLOS issue: I can never remember whether to splice in additional initargs before or after the ones the macro wants to auto-provide. As I mentioned a while ago, auto is good but complete control for the user is also good, so we want them to be able to override something like :-type.
You might think a second reference overrides the first. Nope, it is ignored. But I always forget between occasions when I am doing this and end up doing (describe (make-instance 'xxx :aa 1 :aa 2)) after defining the appropriate class to remind myself.
I just thought of a mnemonic: the initarg list is probably being treated as a plist, so the first of duplicates is the only one seen.
