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