getOptions: Cannot read property 'elm' of undefined

I’m noticing that when calling getOptions here the check for this.options.elm fails here. The exact error is:

Module build failed: TypeError: Cannot read property 'elm' of undefined
    at Object.getOptions (./node_modules/elm-webpack-loader/index.js:37:36)
    at Object.module.exports (./node_modules/elm-webpack-loader/index.js:117:28)

Changing the offending line:

var globalOptions = this.options.elm || {};

…to the following fixes things:

var globalOptions = (this.options && this.options.elm) || {};

…however after studying the code I’m looks as though this.options will always be undefined.

This is with Webpack 4.0.0-beta.0, however I’m also unable to get either of the examples working. Is this a patch worth submitting, or am I missing something?

The very barebones source I’ve been working with is here:

Webpack 4.0.0 is released already. Same problem exists.
