Jose Bollo's PTAGS ( https://gitlab.com/jobol/ptags ) would be
prefect. Any time you declare something to be a container or
enter a namespace you slap a tag on it. Identifying nested
containers would be easy, you'd have multiple tags.
PTAGS unfortunately needs module stacking, but how hard could that be?
