[bug] Rest parameters in async function

[laggingreflex]

Input Code

const a = async(...args) => console.log(args);
const b = async(...args) => a(...args);

b('1');

Babel Configuration (.babelrc, package.json, cli command)

"presets": [
    "es2015",
    "stage-0"
  ]

Expected Behavior

It should output [ '1' ]. Works with node 7 --harmony. Also works without async functions. Problem is only with async functions

Current Behavior

It outputs something big I'm not sure what (global object?)

Module {
    id: 'C:\\...\\test\\utils\\memoize.js',
    exports: {},
    parent:
     Module {
       id: 'C:\\...\\test\\utils\\index.js',
       exports: [Object],
       parent: [Object],
       filename: 'C:\\...\\test\\utils\\index.js',
       loaded: false,
       children: [Object],
       paths: [Object] },
    filename: 'C:\\...\\test\\utils\\memoize.js',
    loaded: false,
    children: [ [Object] ],
    paths:
     [ 'C:\\...\\test\\utils\\node_modules',
       'C:\\...\\test\\node_modules',
       'C:\\...\\node_modules',
       'C:\\...',
       'C:\\...node_modules',
       'C:\\...
