Yes, they were reserved because they were the Java reserved keywords, with the intention that we might add more Java features later in the langauge's evolution. That has no bearing on their use today. Unreserving them wouldn't provide much benefit now. But keeping them reserved still doesn't mean we have any particular need to use them. ~TJ _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
