It provides a functionality that is not matched by any existing proposal or implementation. I gave one example of a creative use for it that helps solve a problem, augmenting native prototypes, that has plagued modern JS frameworks for years. Seems great to me. > I fear it'll stay around, but I hope it will be banished from Harmony. Banishing this could break the web (note current browser/device/ platform support and potential usage) and helps kill innovation. I find that when devs want to banish a feature it's usually because they haven't taken the time to use it properly or creatively. > Merely changing it into a method would be a great improvement.

Using an object as a generic map is full of other gotchas than that of __proto__ and certainly isn't a strong enough reason to "banish" it. To solve this issue as well as others presented by IE I simply prefix the property names burying it in the guts of a user friendly get/set/ unset method. In reality, stepping away from the hypothetical, there hasn't been an outcry of concern about not being able to set a property using the double underscore pre/postfixed proto name. > It would be great to have functions similar to Object.create that > created objects of different [[Class]], e.g., Array.create. Limiting the feature to Array.create is too restrictive a more generic Object.<someHipMethodName> mechanism is better. - JDD -- To view archived discussions from the original JSMentors Mailman list: http://www.mail-archive.com/jsmentors@jsmentors.com/ To search via a non-Google archive, visit here: http://www.mail-archive.com/jsmentors@googlegroups.com/ To unsubscribe from this group, send email to jsmentors+unsubscr...@googlegroups.com
