/**
 * @assertion Execution of a while statement of the form while (e) s; proceeds
 * as follows:
 *   The expression e is evaluated to an object o. Then, o is subjected to
 * boolean conversion, producing an object r. If r is true, then the statement
 * {s} is executed and then the while statement is re-executed recursively.
 * If r is false, execution of the while statement is complete.
 * @description Checks that while body statement is enclosed in implicit extra
 * block.
