Thanks for the link to that article. MiniD no longer uses a "pure" prototype-based object system, but it is still very closely related and faces the same performance issues. Most of the things he mentions I've already implemented, but freezing an object's fields is something I haven't.. frozen namespaces would also be incredibly useful for sandboxed environments. Hm.
