Thought there is the obvious counterpoint: sugaring this one case doesn’t seem worthwhile, given how infrequently operators are defined.  It is quite reasonable to start simple and always require an operator to be a member of a group.  We could eliminate that boilerplate at some point down the road if it is an issue in practice.
