Suggestion for Vue 3.0 : let emit return a Promise array。

[LastHeaven]

What problem does this feature solve?

That can do something after emit event。

What does the proposed API look like?

const loading = ref(false)
const onClick = async () =>  {
 // doSomething
  loading.value = false
  // emit event
  await Promise.all(emit('click'))
  // doSomething
  loading.value = false
}
