The main part of this point is getting rid of @@create, which is far more than an implementation detail. If we can actually pull this off -- in particular, getting rid of the ability to observe half-constructed objects -- then I'd +100 it. It's still worth trying, but as David points out, it's not so easy. /Andreas _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
