+### Top level function (IIFE) is still arrow (on Webpack 5)
+
+That function is injected by Webpack itself _after_ running `babel-loader`. By default Webpack asumes that your target environment supports some ES2015 features, but you can overwrite this behavior using the `output.environment` Webpack option ([documentation]((https://webpack.js.org/configuration/output/#outputenvironment)).
+
+To avoid the top-level arrow function, you can use `output.environment.arrowFunction`:
+
+```js
+// webpack.config.js
+module.exports = {
+  // ...
+  output: {
+    // ...
+    environment: {
+      // ...
+      arrowFunction: false, // <-- this line does the trick
