I've added a commit for this at https://github.com/JCook21/react/commit/a4d0fab19cd11aa95e8a82d37dc61e62b19c4b2f. The only way I could see to have an error triggered when the loop is run if there are no error listeners is to have the loop extend Evenement\EventEmitter. This also means that other components can emit error events through the loop, allowing that event to aggregate all errors in it. I've added code wherever I could to have other components also emit an error event on the loop wherever possible while still emitting their own, existing errors.

I'd be curious to know what you think about this change. I think there are advantages and drawbacks to this but at the moment I can't think of a better way to achieve the result.

I'm closing this for now as it hasn't received any input in a long while and things have changed considerably since this ticket has been opened and it's unclear how much value this would provide nowadays. Please come back with more details if this is still an issue and we can reopen this 👍
