Hmm. I think we're in violent agreement, but our minds don't share the same map for "accessor/mutator". I think of them as "object state retriever/alterer" methods while you appear to think of them as "object attribute retriever/alterer" methods. The difference is subtle but important as an object's state is spread out over all of its attributes (and occasionally its methods too). I suppose your usage is more commensurate with the literature though.
