I think `switch (0) default:` is better, because it's not a loop
so the intent is clear - no continue statements somewhere below
(so it's also better than `do ... while (0);`). Also you might
forget the final break statement with `while` and get an infinite
loop.
This is an occasionally useful general pattern (I use early
returns).
