I have to disagree. For one thing, it is hard to base an exception on the particulars of such a generic case as the one the OP presented, but more importantly, in the context of a question on inheritance, it makes no sense to me to switch over to procedural calling, which disables inheritance. If at some point someone decides to get rid of M::C1::object_method, thereby letting instances of M::C1 use M::object_method instead, then this will break M::C2::object_method as defined by the OP.
