I was refactoring some java to use decorators.  All of the decorators inherited from a class `ThingDecorator`, let's say.  This consisted entirely of:

    SomeType methodName(OtherType otherThing) {
        return decoratedObject.methodName(otherThing);
    }

This is like writing "this thing is a decorator" over and over again, which just drives me nuts as a DRY enthusiast.  Every addition to the activities of this class needs an addition to the class[es] that form the basic un-decorated behavior *and* the decorator, but it's always just "this thing is still a decorator!" all over again.  Is there any way to express *once* that an object is to delegate all non-overridden methods to some member field?
