There is one thing I kept in mind when I implemented this, and which I
didn't say. I should have, because it matters to my eyes.
I was thinking that the default action could be really implemented as
a default action (a default: in the switch, or even an explicit action
per missing case:), not as a pre-action. In languages which are more
properly type checked than C, our trick of typelessly pre-storing $1
in $$ is not a good thing TM.
So I was thinking that having the user make explicit what they want is
a better options. Just as provision for the future.
