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.
Pending Runtime Semantics: PropertyDefinitionEvaluation
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).
