I don't think that is the case actually. There is just far too much 
going on on the C side that isn't necessary once ported to ruby. We 
hand translated a smallish C file and it dropped about 40% off the 
size.

What we CAN do with it is make another feeder into the ruby2c tool 
chain and play with making more analysis tools. I'd LOVE to have 
something that can do the C family so I can extend parse_tree_abc and 
do complexity metrics on C (and with some work objective-c) code. This 
can help us identify the stickier files and get cracking on those first 
(or at least help people decide if they want to take a crack at it :).
