Currently the event bus allows sending and listening to arbitrary events, I got got by that when I pushed a fix using `addEventListener` on a bus across an events renaming, and on the other side the fix did nothing anymore. Entirely my fault, but if the list of events sent on a bus is known and documented (e.g. a jsdoc has `@emits` tags) it would make sense for both the listening and the dispatching to also be validated. This proposal performs validation only when the eventbus is created: - in dev mode (which also requires being in a component context) - if an iterable of events is passed to the ctor The dev-mode check might be overkill but it seems like a good idea at least for an initial version, as the validation does have a cost however low, and validation errors can occur essentially anywhere.
