This is the way to get programs over 500 lines, and it doesn't increase the attack area as much as you'd think, since you can essentially hard-code the addresses of outside contracts into your code--it's not a combinatorial explosion.

You should call Gavin Wood and tell him that :D

That makes sense, thanks. I hadn't thought of making it hard-coded (or just set at construction). The examples I'd seen were "upgradable" tokens.

Yeah, I did a lot of upgradeable stuff early, but have since moved to more hardcoded stuff for that exact reason.
