Thanks for the report, we check the initargs for shared-initialize
methods, but not for methods of initialize-instance
itself. Therefore, we don't find that :x2 initarg (because we only
look into shared-initialize methods) and thus the
arg check fails. I'll hopefully be able to fix this during the weekend.
