    SpreadElement : ...AssignmentExpression

    1. Let spreadRef be the result of evaluating AssignmentExpression.
    2. Let spreadObj be ? GetValue(spreadRef).
    3. Let iterator be ? GetIterator(spreadObj).
    4. Repeat
       a. Let next be ? IteratorStep(iterator).
       b. If next is false, return nextIndex.
       c. Let nextValue be ? IteratorValue(next).
       d. Let status be CreateDataProperty(array, ToString(ToUint32(nextIndex)),
          nextValue).
       e. Assert: status is true.
       f. Let nextIndex be nextIndex + 1.

    PropertyDefinition:...AssignmentExpression

    1. Let exprValue be the result of evaluating AssignmentExpression.
    2. Let fromValue be GetValue(exprValue).
    3. ReturnIfAbrupt(fromValue).
    4. Let excludedNames be a new empty List.
    5. Return CopyDataProperties(object, fromValue, excludedNames).
