[Laszlo-dev] Requiring LzMiniNode as event sender/receiver

[P T Withington]

Yeah, I'm trying to tighten up the rest of the args so we get 'early  
warning' when someone is trying to do event-y things with non-events  
(a major source of leaks).  Once that is done, I think I can make our  
event system much more efficient, and maybe even eliminate the need to  
remember all your delegates for cleanup on destroy.
