import { defineComponent } from '@vue/runtime-core'

export default defineComponent({
  name: 'App',
  setup () {
    const waitingForAutocomplete = true;

    const a = {
      wait // get `waitingForAutocomplete`
    }

    return {
      wait // don't get any completion
    }
  }
})

🙁 Actual behavior

We can't get any completion for object literal shorthand in setup return.

🙂 Expected behavior

Like common object literal shorthand.
