/// @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.
