Thanks for your answers Ludovic and Clinton.

By the way, I have a question about threads: is there a way to kill a
running thread? For example when the current game screen changes, all
current scripts are terminated. Or does this need to be implemented

That's a pro, but there are cons too :/
- this kind of game engine has hardly anything runnable in parallel
- all the game globals need to be properly mutex'd
- or threads executions need to be serialized which defeats the point
Another pro though is that all of us masochists love debugging
multithread programs ;)

I'll try these solutions with my toy project and see how they fair
with performances/complexity :)
