How to solve this basic ES6-module circular dependency problem?

[/#!/JoePea]

Oops, I forgot the export in module C:

```js
// --- Module C

import A from './A'
import B from './B'

console.log('Module C', A, B)

class C {
    constructor() {
        // this may run later, after all three modules are evaluated, or
        // possibly never.
        console.log(A)
        console.log(B)
    }
}

export {C as default} // export!
```
