+Behaves identically to [`server.events.emit()`](#server.events.emit()), but also returns an array of the results of all the event listeners that run. The return value is that of `Promise.allSettled()`, where each item in the resulting array is `{ status: 'fulfilled', value }` in the case of a successful handler, or `{ status: 'rejected', reason }` in the case of a handler that throws.
+
+Please note that system errors such as a `TypeError` are not handled specially, and it's recommended to scrutinize any rejections using something like [bounce](https://hapi.dev/module/bounce/).
