Given:

// ./whatever.js
export { someThing }
export default class Whatever { /* ... */ }

Warn on:

import Whatever from './whatever'
Whatever.someThing // Reported: someThing exported as named export alongside Whatever.

Would be unusable/noisy if there are static fields on a default export that match exported fields (i.e. lodash) but that seems fine.

I.e.

import _, { isEmpty } from 'lodash'

would report on _.isEmpty, etc. (assuming lodash exported ES modules). so you could only use the default export for chaining (i.e. _(thing).isEmpty()) which makes sense, otherwise you'd want * as _ anyway.

I have an implementation of this rule that I'll clean up and send as a PR either tonight or tomorrow.
