+  3. Let errorsList be ? IterableToList(errors).
+  4. Set O.[[AggregateErrors]] to errorsList.
+  ...
+  6. Return O.
+
+  Runtime Semantics: IterableToList ( items [ , method ] )
+
+  1. If method is present, then
+    ...
+  2. Else,
+    b. Let iteratorRecord be ? GetIterator(items, sync).
+  3. Let values be a new empty List.
+  4. Let next be true.
+  5. Repeat, while next is not false
+    a. Set next to ? IteratorStep(iteratorRecord).
+    b. If next is not false, then
+      i. Let nextValue be ? IteratorValue(next).
+      ii. Append nextValue to the end of the List values.
+  6. Return values.
+
+  GetIterator ( obj [ , hint [ , method ] ] )
+
+  ...
+  3. If method is not present, then
+    a. If hint is async, then
+      ...
+    b. Otherwise, set method to ? GetMethod(obj, @@iterator).
+  4. Let iterator be ? Call(method, obj).
+  5. If Type(iterator) is not Object, throw a TypeError exception.
+  6. Let nextMethod be ? GetV(iterator, "next").
+  ...
+  8. Return iteratorRecord.
