probably in a earlier thread of this topic that I did't pay a lot of attention too.

One of the main complaints people made about symbols was that it's not possible to do userland coordination across realms. While I don't think we have to solve that for ES6, my examples demonstrate that with a registry symbols absolutely can provide cross-realm coordination while tangibly beating out string conventions for ergonomics/usability/readability.

No the ergonomic issues are good arguments against using GUID for the the actual property keys.  One of the attractions of the "@iterator" form is that it has pretty good ergonomics. If somebody wanted to use them but not not clutter the actual string with a name space qualifier (which may be a bit noisy, but is still a lot better than a GUID) they would have to use a Registry to access a friendly string property key.
