I agree. In fact, I don't see a reason to make it even that simple. My understanding was that there is wide agreement that invoking constructors without 'new' should be discouraged, and that functions behaving differently for Call and Construct are considered a legacy anti-pattern. In the light of that, I'm stilling missing the compelling reason to introduce new^ at all. In particular, since TDZ for `this` allows you to make the distinction fairly easily even without a new construct, if you are so inclined. /Andreas _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
