Thats quite a good way of representing things, I was thinking of a
more callback based interface but generators do indeed work and are
elegant. But what is yielded may have to be elaborated upon.

I would like to see an embedded language replace more than just sgsl,
one that may also provide an interface for custom ai, or one that
could be used to describe random maps (for Giszmos new system).

Oner thing forwarned, scripted unit behaviour should be avoided,
because this alters the gameplay of the game, and other "scripts" will
become dependant on this script either being there or not being there.
