 * @assertion Execution of a case clause case ek: sk of a switch statement
 * switch (e) {
 *   label11 … label1j1 case e1: s1
 * …
 *   labeln1 ..labelnjn case en: sn
 *   label(n+1)1 ..label(n+1)jn default: sn+1
 * }
 * proceeds as follows:
 * The expression ek == id  is evaluated to an object o which is then subjected
 * to boolean conversion yielding a value v. If v is not true, the following
 * case, case ek+1: sk+1 is executed if it exists. If case ek+1: sk+1 does not
 * exist, then the default clause is executed by executing sn+1. If v is true,
 * let h be the smallest integer such that h >= k and sh is non-empty. If no
 * such h exists, let h = n + 1. The sequence of statements sh is then executed.
 * If execution reaches the point after sh then a runtime error occurs, unless
 * h = n + 1.
 * @description Checks that falling through produces a compile error, if
 * the current clause is not empty case clause and not the default clause.
