Migrating from Coffeescript to ES6

I’m trying to slowly migrate a large project from Coffeescript to ES6.

However, having both coffeescript and grigio:babel in a project results in the following error from a .coffee file. Is there a workaround for this that would allow both to work for the interim period of migration?

Hmm, this had something to do with using the export class syntax of ES6. Will follow up with more information.

import/export aka ES6 modules is not yet supported.
