Is there a way to exclude a function from obfuscation?

In one of my project we have WorkerFn function that executes within WebWorker environment. We create it in this way:

function WorkerFn(root) {
  //here is worker code
}

url = URL.createObjectURL(
  new Blob([ '(' + WorkerFn.toString() + ')(this)' ], { type: 'text/javascript' })
);

ww = new Worker(url);

This is only place that breaks after obfuscation, because this function executes in clean environment (WebWorker) and doesn’t have global function to resolve names.

I know the workaround to add every name into reservedNames array, but it has serious downsides:

• it prevents names from obfuscations in other places of script
• it is tedious process and breaks every time source code is changed

Is there good solution to avoid obfuscation of this chunk?
