      So glad we didn’t enable decorators in CRA despite the popularity. The stage 2 version looks quite different to me.https://twitter.com/left_pad/status/897470712277028864 …

      Maybe I’m wrong so please help me understand. But my impression is you can’t use HOCs directly as decorators anymore. Is this accurate?

      In other words it seems like class decorator now has to return an object. Whereas in the past it could just return a new function alone.

      No I'm almost certain that's wrong. Class decorators are just about the same as they were, except now take a second arg.

      cc @wycats, curious if you could clarify this! I’m getting lost. Is Klass => Klass still a valid decorator?

      No. We moved to descriptor, which gives a lot more power (without too much complexity) but isn't quite that simple.

      But you can still do Class => { * mutate Class * //return undefined } right?

      But your usage won't. You'll just have to change the decorator once.

      You don't mutate the class, you supply additional members, which get added. It's not that bad. I should write a microsite.

          In case of connect() it returns a different class altogether (as common for HOCs).

          You can probably accomplish your use case with class finishers, but @littledan and I recently changed the spec to require a subclass iirc

          We should look at this use case to see if "constructor replacement" is a feature we need to add back.

          By that do you mean returning a NEW constructor? ie `Class => class extends Class{}`? If so yeah, that would be incredibly handy.

          That's not what HOCs do though. They return a completely different class.

          Right Class => class extends Class ie they return a NEW class, like connect. Did you reply to the wrong tweet? :)

          Ah sure. Doesn't *have to* be Class => class extends Class could just be Class => class { /* somehow ref Class */ } either way - NEW class

          Corollary to the above: this would be a massive breaking change to not only stage 1, but also TypeScript class decorators.

          The extra power allows you to add public and private fields, which is great when you need some state for a getter you're making.

          Wouldn't supplying additional members == mutating? Ie you're mutating the class - changing it. Am I misunderstanding you?
