Error: unknown node of type "Literal" with constructor "Object"

[Rush]

I wanted to give a fast-async a second shot but unfortunately it didn't work. I did nail down the problem to this piece of code though.

let foo = async () => {
  for(let bar of []) {
    await Promise.resolve();
  }
};

Full error:

      throw err;
      ^

My .babelrc:

{
  "presets": ["es2015-node6"],
  "plugins": ["transform-decorators-legacy", "transform-class-properties", "transform-es2015-modules-commonjs", "transform-strict-mode", "transform-es2015-spread", "transform-es2015-destructuring", "transform-es2015-block-scoping", ["fast-async", {
    "compiler": {
      "sourcemap": true
    }
  }]]
}

To reproduce:

wget http://x.rushbase.net/ad01410a94ea35c0d57d86ddfe4eedd4da29c877/babel-fast-async-test.zip
cd babel-fast-async-test
npm install
