? Depends on your application, I suppose. I've heard bad things about 
the speed of C++ vs. hand-coded assembler. But there are very few 
situations any more in which I'd willingly choose the latter.

We used Boost.Signals as the central event system for an interactive 
game. Mouse movements, UI controls, internal notifications, frame 
updates, all used that event system. It was fine for our purposes.

Beware of premature optimization.
