 * @assertion Execution of a statement s of the form yield e; proceeds as
 * follows:
 *    First, the expression e is evaluated to an object o. If the enclosing
 *  function m is marked async* and the stream u associated with m has been
 *  paused, then execution of m is suspended until u is resumed or canceled.
 *    Next, o is added to the iterable or stream associated with the immediately
 *  enclosing function.
 * ...
 * If the enclosing function m is marked sync*  then:
 *   - Execution of the function m immediately enclosing s is suspended until
 *   the nullary method moveNext() is invoked upon the iterator used to initiate
 *   the current invocation of m.
 *   - The current call to moveNext() returns true.
 *
 * @description Check that call to moveNext() upon the iterator, used to
 * initiate the current invocation of m,  returns true
