there is nothing to do from webpack @alexander-akait . user should correctly mark side effects with `sideEffects` flag.

cc @alexander-akait

Is it possible to contribute? or this issue still is in discussion?

@evilebottnawi I will take this.

@evilebottnawi should we skip comments in `.toString()` method? Currently https://github.com/postcss/postcss-selector-parser/blob/master/src/__tests__/util/helpers.js#L24 we expect that comments will be in output

Sorry I was a bit stuck with stringifying comments correctly and gave up =) I hope I will find time on the next week or will create WIP PR.

hm.. I think `parser.worker` should work here.. Since structure should be` (new URL(...))`

for "base" audio there is https://developer.mozilla.org/en-US/docs/Web/API/BaseAudioContext/audioWorklet for custom thing there is a workaround to MyAwesomeWorker.js ``` export default whateverWorker.a.b; ``` index.js ``` import Worker from "./MyAwesomeWorker"; // use Worker ```...

@evilebottnawi we can add this to defaults https://github.com/webpack/webpack/blob/master/lib/dependencies/WorkerPlugin.js#L31 @sokra approve?
