Thanks! I believe the idea is great, but I am not really sure if this is useful enough without handling anon namespaces properly. It's very rare that someone has a class/struct in a cc file, that isn't in an anon-namespace.

Would you mind evolving the patch (and the infra) to work for method-definitions inside anon namespaces?
