Hmm, i used Functors and Closures in jass for passing commands to the

realtime thread and wrote a small article about it.
http://178.63.2.231/~tapas/wordpress/?page_id=45
Coupled with a poor man's garbage collection scheme using

boost::shared_ptr's this was a quite quick way to hack up jass. There's

no need to introduce new types if you want to do something new. Actually

there's only exactly one type that gets passed through the command

ringbuffer and that is boost::function. See e.g.
https://github.com/fps/jass/blob/master/engine.h
and
https://github.com/fps/jass/blob/master/main_window.h
I agree that this method doesn't necessarily scale to other kind of

applications and it also might be a bit more error prone than a well

thought out event system using types that cover all bases, it does make

for a quite good solution for an app of the scope of jass..
Have fun,

Flo
