Let's just say they are opposing proposals.

One obstacle in this scheme's way is that there are material
differences betewen the various metavariables ($$return,
$$vars, $$parms, $$locals, and perhaps others in the future).
They can't all match "*".  Further, there is interplay with
.return probes' optional saving of invocation-time variables.
