This is (surprisingly) almost identical to the Reactivity Transform explorations we did in Vue: https://vuejs.org/guide/extras/reactivity-transform.html

  let count = $ref(0)

  const double = $computed(() => count * 2)

  watchEffect(() => {
    console.log(double)
  })

We started experimenting with this ling of thought almost 3 years ago:

- First take (ref sugar), Nov 2020: https://github.com/vuejs/rfcs/pull/228

- Take 2, Aug 2021: https://github.com/vuejs/rfcs/pull/368

- Take 3, Nov 2021: https://github.com/vuejs/rfcs/discussions/369

We provided it as an experimental feature and had a decent number of users trying it out in production. The feedback wasn't great and eventually decided to drop it. https://github.com/vuejs/rfcs/discussions/369#discussioncomm...
