> So, after thinking about it for very long time, I have officially decided to not support ASTs and tree grammars in honey badger. I took the plunge today and yanked it all out. It dramatically simplified everything, of course. Removing code is one of my favorite things :)  Anyway, I've done the deed. Getting honey badger to support ASTs in a fully backward compatible manner was going to be difficult anyway. v3 works and is stable. moving AST code to v4 with simply make it less reliable.
