Meteor 1.3b11 import issue?

Either this is a bug, or I’m dumb and don’t know JavaScript nearly as well as I thought…

This code fails (test === undefined):

import * as routes from '/client/routes.jsx';

const test = routes.ROUTE_DASHBOARD; //yes, this is truly defined and exported

But this works:

import * as routes from '/client/routes.jsx';

export default class MyComponent extends Component {
  render() {
    const test = routes.ROUTE_DASHBOARD; // test === 'dashboard'
  }
}

Is there some reason this imported constant wouldn’t be available outside the scope of the React component?
