These threads (we had a recent flare-up about LOCAL, as some might
recall) point to the worst thing about Old Scheme: not only did they
leave the semantics undefined, they ALSO didn't have the courtesy to
provide a reference compiler that actually produced unexpected output,
thereby compounding confusion (resulting in unknown unknowns).
