I thought about that too.  I think I prefer Daniel's formulation
with the new function, but I'm not especially set on that.

An advantage of using a new function name is it'd be more obvious
what's wrong if you try to back-patch such code into a branch that
lacks the feature.  (Or, of course, we could back-patch the feature.)
