Shorthand for current events in source

[marrus-sh]

yeah yeah this isn't really necessary but writing "LaboratorySomeEvent" 50 bajillion times is boring and what if the event name changes and so on. It'd be cool if there was just a keyword that just always referred to the current event or whatever. You'd probably have to do some magic in dispatch to make this happen.

Now that onError isn't used (as of 4859a4b) this Issue is irrelevant
