Feedback for ES decorator proposal

I’ve been contacted by @wycats (who is the champion of the ES decorator proposal at TC39) to provide feedback for the proposal from framework authors’ perspective, and since this library (and vue-property-decorators) is the primary use case where Vue leverages decorators, I’m hosting the thread here.

I know there are a few discrepancies between ES and TS decorators, but am not 100% clear on the details. Ideally, I hope we can use vue-class-component and vue-property-decorators in both ES and TS contexts.

Would appreciate thoughts from @ktsn and @kaorun343 on this topic.

Afraid to sound stupid, but after almost two years I’m still not getting the real value of decorators.

I must agree with @carlsmith https://github.com/coffeescript6/discuss/issues/9#issuecomment-235975114 that decorators are just a fancier way to write wrappers.

And it even doesn’t look natural in JavaScript, since it would be the only operator (probably, alongside the case 'value': operator), which breaking a regular JS premise to define strict scopes with {}.

It just looks ripped off from Python and alienly slapped on syntax with quite different philisophy.

In worst scenario it should be something like

@Component() {
  Class Test {
    // ....
  }
}

Yes, we intend to align once the proposal stabilizes.
