A minor qualm compared to all the other things being discussed here, but isn't it confusing to have "keys" mean two different things? In ES5 usage it means "enumerable, string-valued" whereas in this proposed Reflect.ownKeys it means "no qualifiers: non-enumerable OK, symbol-valued OK". From an ES5 perspective, "property names" (as in getOwnPropertyNames) are "enumerable or non-enumerable string-valued" whereas "keys" are "enumerable string-valued." Ideally there would be a new designation for non-string–valued. _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
