| 01:42 | <ljharb> | and a userland class will be wrapped by a branded object. |
| 15:36 | <bakkot> | Iterator.from checks instanceof Iterator and returns the original object if that returns true |
| 15:36 | <bakkot> | so no, it does not provide a common brand |
| 17:33 | <snek> | without first class protocols the only ways to check if something is an actual iterator is either rely on the prototype or exhaustively interrogate its methods |
| 18:17 | <rbuckton> | This is one reason why I'm still wary of using Iterator rather than an Iterable. |
