I am making a program that I am trying to change the (lua) API in to 
make it better suited for evolution.

The program is rather like glut is, but written using Cocoa's API 
(objective-c / mac) to host it, but still opengl. Lua runs the actual 
scripts.

Right now the events work similar to glut.

A trimmed down example:
- --
function reshape(w,h)
	...
end

System.register_reshape_func(reshape)
- --

What happens is that it will load up the module an execute it, so that 
the functions become registered. Then the script essentially is done 
until an event is fired by resizing the window.

This is fine for basic stuff, but I want to make it more like how 
windows does it.

A hypothetical example:

- -- performed in a loop
e = Event.GetEvent()

if e.type == WM_RESIZE then
	...
end
- --

The key being GetEvent.

Where the magic here is, and I am hoping can be done in some way...

GetEvent 'blocks' until an event is received, in exactly the same way 
as the original example worked.

From my limited exposure to other languages continuations would work 
here if they were available :-). It has been suggested coroutines might 
be the way, but I do not know even of that.

:-) Merci pour l'assistance
