Right -- this is important and it is a deoptimer for optimizing implementations, but they can cope. The real problem is for JS hackers who cannot be sure their foopey typo (when they meant foopy) won't resolve to something else, accidentally or maliciously. > 2.

Developers I talk to really want early error on typos, it's a no-brainer. Dmitry, if you mean something other than revoking this win of Harmony lexical scoping, please correct me. Otherwise, I do not see any good in reinjecting the global object (directly or via some kind of proxy) onto the scope chain. /be _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
