export default {
  input: './index.js',
  output: {
    file: 'dist/index.js',
    format: 'cjs'
  },
  plugins: [
    babel.default({
      babelHelpers: 'bundled',
      presets: [
        [
          (await import ('@babel/preset-env')).default,
        ]
      ],
      comments: true,
    })
  ],
}

function a() {
  return _a.apply(this, arguments);

• Excepted result:
