Name sounds like a stripped-down uninterned symbol (http://bit.ly/bY3Jkg) to me. It's an object with a magic attribute that says, unlike any other object you might try to use it as a property name, it is not coerced into a string first. And it is compared by identity when looked up. And it is invisible to (all?) enumerations of property names. I have to wonder if it would be a worthwhile generalization to be able to confer these magical attributes on arbitrary objects? This might allow more experimentation with namespace ideas. _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
