FWIW, I'll second this reasoning: to me, it kind of goes with the
territory of devising a smart API that sometimes it's ok to have a
bit of complexity under the hood, when the effect is to simplify the
constructs the programmers will regularly /use/, or make better use
of compiler type checking. As it appears that EVENTHANDLER_INVOKE
does both, it looks like a smart design to me.
