Indeed. The reason dunder doesn't work is that it's used in user-land due to the spec's usage, which means that it's not implausible that some library uses __iterator__ already for a different (or even similar) purpose. The @ prefix dodged that bullet today (although it may introduce generated-code hazards), but it opens up exactly the same problem for the * next* time we need a new unique name. > > ______________________________**_________________ > es-discuss mailing list > [email protected] > https://mail.mozilla.org/**listinfo/es-discuss<https://mail.mozilla.org/listinfo/es-discuss> >
