Oh, this is specifically a JSC issue, it's not a spec related problem -- we have API and ABI that guarantee these bits of weirdness are possible, so it's simply going to be a matter of trying to work around them, or otherwise mask the behaviour without impacting existing clients. No change in the spec can effect our existing API -> property attributes are still DontDelete, etc in C code, because anything would break source compat, what fun! --Oliver _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
