Alternative to ReasonReact and JSX support?

Can this be used as an alternative to ReasonReact, and does it have JSX support as well?

show a .re example in readme

Users who prefer reason over ocaml syntax and who are unfamiliar with the usage of annotations like let [@hook] may have a hard time understanding where the annotations go in a Reason formatted codebase.

Putting this example:

let useDoubleReducer =
 fun [@preact.hook] (reducer, initialValue) ->
  let[@hook] state, dispatch = P.useReducer reducer initialValue in
  let dispatchTwice action =
    let () = dispatch action in
    dispatch action
  in
  state, dispatchTwice

let make =
 fun [@preact.component "HelloHooks"] () ->
  let reducer state action = state + action in
  let[@hook] state, dispatch = useDoubleReducer (reducer, 0) in
  P.button [ P.onClick (fun _ -> dispatch 2) ] [ P.int state ]

into the ReasonML playground outputs this:

let useDoubleReducer =
  [@preact.hook]
  (
    ((reducer, initialValue)) =>
      [@hook]
      {
        let (state, dispatch) = P.useReducer(reducer, initialValue);
        let dispatchTwice = action => {
          let () = dispatch(action);
          dispatch(action);
        };

        (state, dispatchTwice);
      }
  );

let make =
  [@preact.component "HelloHooks"]
  (
    () => {
      let reducer = (state, action) => state + action;
      [@hook]
      {
        let (state, dispatch) = useDoubleReducer((reducer, 0));
        P.button([P.onClick(_ => dispatch(2))], [P.int(state)]);
      };
    }
  );

As someone who does not know where annotations are supposed to go in Reason formatted code it is unclear if this translation is in fact correct.

PS: thanks for your work, really like the hooks validation at compile time 👌

Proposed solution
