mmmmh, is that optimizer purely rule based? if yes, maybe adding something 
like daniel dallmanns opt65 could improve the result a bit? (although i

I'm the commander. See? I don't need to explain. I do not need to explain why 
I say things. That's the interesting thing about being the president. Maybe
