Why can't I import a default export with "import ... as" with BabelJS

In version 5.6.4 of BabelJS, I seemingly cannot "import ... as." Here are examples of what I am trying to do:

In file 'test.js':

export default class Test {};

In file 'test2.js' (in the same directory):

import Test as Test2 from './test';

I have also tried to do:

import {Test as Test2} from './test';

Even though it says nothing about that here: http://babeljs.io/docs/learn-es2015/#modules

And only uses brackets in the non-default syntax here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/import

Has anyone done this successfully?

EDIT: It is absolutely because of the default keyword. So, in this case, the question becomes, does anyone have any links to documentation that states that I should not be able to alias a default import? ECMA or Babel.

You can import the default export by either

import Test2 from './test';

or

import {default as Test2} from './test';

The default export doesn't have Test as a name that you would need to alias - you just need to import the default under the name that you want.

The best docs I've found so far is the article ECMAScript 6 modules: the final syntax in Axel Rauschmayers blog.
