the fact that I can incrementally fix something and then run it against the known failures makes doing compatibility work via gauntlet pure joy. I've been using gauntlet to compare parsetree to rubyparser and to do round trips between rubyparser and ruby2ruby. It's finding _a lot of stuff for me to work on.
