In my experience the less grammar elements a DSL has the better, unless

I ran the code you provided, error occurred as you expected, but we
wish it could run well. We have to refine the implementation...
groovy> class X {
groovy> private bar(){1}
groovy> def b = this.&bar
groovy> }
groovy> println new X().b()
groovy> class Y extends X {}
groovy> println new Y().b()
the implementation will have to provide the caller class as part of the
method choosing, thus as part of the method reference... unless we
totally rewrite that and make something entirely different... maybe I
would experiment with using a callsite as backing for the handle.
bye Jochen
