It sounds like you are proposing a second name for `String.prototype[Symbol.iterator]`, which does not sound very useful. A property for the string's "real length" does seem somewhat useful, as does a method that does random-access on "real characters." Certainly more useful than the proposed symbolAt/at. But I suppose we can pave whatever cowpaths arise. My proposed cowpaths: ```js Object.mixin(String.prototype, { realCharacterAt(i) { let index = 0; for (var c of this) { if (index++ === i) { return c; } } } get realLength() { let counter = 0; for (var c of this) { ++counter; } return counter; } }); ``` This would allow you to e.g. find the character in the "real" middle of a string with code like ```js var middleIndex = Math.floor(theString.realLength / 2); var middleRealCharacter = theString.realCharacterAt(middleIndex); ``` _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
