could you provide both profiles without arrow function and with it?

@Rush set `output.environment.arrowFunction=false`, see https://webpack.js.org/configuration/output/#outputenvironment . this should help

@joemarshall didn't get what you mean.. webpack does nothing with ```js this._worker = new Worker(window.URL.createObjectURL(blob)); ``` since this is not statically analyzable

@sokra is it still an issue?

there is an opened PR https://github.com/webpack/webpack/pull/14661

@alexander-akait what should we do here?

I think parser does not support them.. (`@webassemblyjs/wasm-parser`) . Right now there is no workaround for this.

ok, webpack should implement for shared modules package.json more smart resolving..
