      @wycats @brendaneich let's not pretend that the organic patterns that devs have grown to work-around JS quirks haven't restricted future JS.

      @getify @BrendanEich I have literally been the #1 advocate for considering existing patterns on TC39. It's not an absolute.

      @getify @BrendanEich ES5 code was allowed to throw in the constructor, and that was actually a quite common defense!

      @wycats 's decorator proposal I think shows the true power and benefit of class. *THAT*'s the biggie, for me at least. @getify @BrendanEich

      @adamrackis @wycats @brendaneich further reinforcement of my OP… decorators are distinctly "class-like" and alien to prototype-only patterns

      @getify @AdamRackis @BrendanEich ES5 constructors quite often throw when called, just in weird ways. What makes you think otherwise?

      @getify @AdamRackis @BrendanEich you are making an empirical claim: ES5 constructors very rarely throw when [[Call]]ed. Self evidently false

          @getify @AdamRackis @BrendanEich http://this.foo  = bar or http://this.foo  in an ES5 strict constructor will throw 100%.

          @getify @AdamRackis @BrendanEich in a sloppy constructor http://this.foo  = bar erroneously adds to the global object.

          @getify @AdamRackis @BrendanEich code that relied on blindly calling a constructor and it never throwing is broken in ES5, full stop

          @wycats @adamrackis @brendaneich you'll notice my example code didn't rely on that. it used .call to provide a substitute context.

          @getify @AdamRackis @BrendanEich your notion of compatibility does not match mine. Let's agree to disagree.

          @wycats on a related note, I've been exploring your decorators more than a little - really well done.https://www.npmjs.com/package/easy-express-controllers …

          @wycats @adamrackis @brendaneich i'm making a claim: vast majority of ES5 constructors i've seen either had no guard, or the re-new guard.

          @wycats @adamrackis @brendaneich and that virtually none of them had explicit `throw`. yes i'm well aware of strict-mode undefined `this`.

          Replying to @wycats

          @wycats @adamrackis @brendaneich it matters b/c ES6 class constructor now has explicit throw if you use .call… as my gist showed.
