What I was trying to say is that using C as an intermediary language
reduces effort. Of course it is /possible/ to do the optimizing
yourself, it is just more work.
I think that "reducing effort" is a pretty damn good reason for doing
something in a specific way. I hope that answers your "why the hell"
