Craig and Zhanyong have an analogous dump output built around RecursiveASTVisitor. Its output is also structured in a form to make it easy to write FileCheck-based tests for IIRC. I believe they were intending to commit that, but had held off thinking the existing system was "Good Enough". If they can contribute this, would that be a good place to focus effort on this front? I think it is already more complete than this dumper, although I've not audited it by any means. > > I am not wedded to XML, but there are much better visualization / > exploration tools for XML than for not-really s-exprs. :) > > > Also, why only in assert builds?
