Hi, In the process of trying to update [mocha](/mochajs/mocha)'s dependencies, I found diff >= 2.0.0 breaks in IE8. This is why: ``` js exports.default = Stuff; ``` `default` cannot be used this way in IE8. It _can_ be used like this: ``` js exports['default'] = Stuff; ``` I did find [this module](https://github.com/coudly/babel-plugin-transform-es3-modules-literals), but I couldn't get it to work.
