Ehm. Why do you need @ ?

  function getSomeData: JSValue;
  begin
    asm
      /* return a data structure */
      return {first:"hello",second:"hello2"}
    end;
  end;

or
  function getSomeData: JSValue;
  begin
    asm
      /* return a data structure */
      Result= {first:"hello",second:"hello2"}
    end;
  end;

Should do what you need.

In each case, parsing the javascript is not planned for the near future.
