Type not inferred for `export {...}` (works with `export const ...`)

[giacomoran]

Describe the bug

Hi!

Given the component below, a bind:this will return a component instance where some read-only exports are typed and some are not:

<script lang="ts">
  const foo = "Vittorio Alfieri";
  export {foo};            // Type not inferred (any)
  export const foo_ = foo; // ✔ inferred (string)
  export const bar = 41;   // ✔ inferred (string)
</script>

The export {...} syntax would allow our code to be cleaner and more concise.
