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

{
  "presets": [
    ["es2015", { "loose": true }]
  ],
  "env": {
    "ava": {
      "presets": [
        ["es2015", { "modules": false }]
      ]
    }
  }
}

Expected Behavior

When run babel with env ava, it's should not compile es2015 module code.

Current Behavior

Compile es2015 module into commonjs.
