/// @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.
