The `delete` operator applied to a non-reference just does nothing (no error is thrown), whereas an assignment to a non-reference did throw an error. I guess that there is some BC risk for trying to turn a non-error into an early error, not worth the advantage? —Claude _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
