This allows modeling the interface purely on the desired common behaviour, whereas the getter approach requires including the getters in the interface out of necessity rather than need. It also precludes the possibility of adding more member fields in a "derived class" and using them in function overrides. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
