-> Compile objects with duplicate keys to valid strict ES5. This plugin actually converts duplicate keys in objects to be computed properties, which then must be handled by the [transform-es2015-computed-properties](http://babeljs.io/docs/plugins/transform-es2015-computed-properties) plugin. The final result won't contain any object literals with duplicate keys.
