I saw that message, but I didn't notice that question then. I saw only a proposal for a syntax that would insert a non-exit clause inside the following ordinary clause. My reply was that that syntax seemed unnatural for what the feature does. Now I see you meant to propose a different feature, one which would make bindings that apply only to the following clause. Such a feature could occasionally be useful, but not useful enough to justify adding an additional feature. It would not be an adequate replacement for the non-exit clause feature. I've chosen the term "non-exit clause" because that name states the feature's overall effect, and its purpose. "Falling through" is just a part of the effect. -- Dr Richard Stallman (https://stallman.org) Chief GNUisance of the GNU Project (https://gnu.org) Founder, Free Software Foundation (https://fsf.org) Internet Hall-of-Famer (https://internethalloffame.org)
