What? That would just cause the event handler function to return a generator object, which the browser would not use or do anything with. It would have no effect.

Subject: generators inside DOM events
I am not sure this has been discussed already but I wonder what would happen if `yield` is used inside an event such 'beforeunload', 'unload', or even 'click' and others DOM related events.
1. it's a UA trap potentially making impossible to leave a page or complete a user meant action
2. not even transpilers can solve cases like this (i.e. a still valid event eventually stopped after some generator logic where if simulated the event would be expired at the time the function will be invoked)
