Holy shit. This is incredible. I love Emacs but it&#x27;s so sad that the stewardship of this amazing piece of software is in the hands of someone who would rather keep the feature-set substandard because of vague fears that someone might steal the AST&#x27;s from his precious GCC.<p>I wonder what would be the problem with someone using libclang to generate the same AST information in a much more convenient fashion. Will it break the GPL in some way?
