Yes. As I pointed out later in that mail, having such an implicit constant defined in an outer function and used in a nested function should be fine but some engines may not optimize it yet. And I suggested that if you find examples of this not working right you should file bugs against the engines. But it turns out that if it's done at global scope then constant-inferring the variable is even easier than if it was local, so that kind of idiom definitely shouldn't require language help. -Filip > > -Boris > _______________________________________________ > es-discuss mailing list > [email protected] > https://mail.mozilla.org/listinfo/es-discuss _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
