   * bundled files and import names to correspond to names as exported by
   * bundles.

      // have to use generic `enter` and walk all nodes until that's fixed.
      // TODO(usergenic): Switch this to the `Import: { enter }` style
      // after dynamic imports fully supported.
      enter(path: NodePath) {
