Alright. First question I have about such a multi-pass tool would be how best to do the rewriting. Should we completely apply the previous pass' changes, re-parse, then move on to the next pass? For simple transforms rewrites probably wouldn't conflict (e.g. template space removal, nullptr usage) but one could easily forsee one pass making a change that might affect a later pass. Let's not forget that physical rewrites from one pass may overlap with rewrites from another. Assuming yes, I presume we shouldn't be writing out to disk every time but rather changing an in-memory buffer?
