Hi hans-martin

Yes I look at the ASt and for example the fact that each node knows its 
parent is just good.
Then I was REALLY fed up with Squeak AST to be lost in comment node and 
stuff like that. I'm tired to lose my time with Squeak.

This is what we will do in the future. I also would suggest Squeak to 
throw away the old parser and AST and rebuild everything needed based 
on RB parser and AST.

But you know between my wishes and what we obtain there is a gap.
