Thanks for giving a try. I have an initial question about the code. It seems like it stores all the "reports" and all the "declarations" in flat lists. Then we flush the reports once per compilation unit.

This means we still have to do a lot of work to associate reports with declarations.

What I had in mind was to basically do the association when `endDecl` is called. E.g. once you see a field declaration, at that point you can defer all the lint warnings that have been created for that field. This probably needs some `startDecl` (maybe). I'm sure you considered this alternative -- I'm curious as to why it was rejected?
