Anyway, I thought more about consistency than about usefulness; because for each method, there are several potentially useful return values. (For example, the `.set()` and `.add()` methods could arguably return the value just set/added, just like `foo.bar = value` is `value`, or `foo.appendChild(node)` is `node`, which I find both positively useful in practice.) —Claude _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
