Sorry, can you just reduce the PR to just this line? I'm really sorry for taking up your time on this Sacul. After staring at this more, I realised the original function watcher idea works, but needs a lot more work. I think this might be too complicated for a contributor to take, so I'll take over. Thanks for opening the issue again and for spotting this mistake of mine!
