Very much like the thinking.

I guess it isn't feasible at this point to change `internal` to mean file
scoped? That could avoid the need for another qualifier by simply
leveraging the default of module scope for things without an access
qualifier.

As you know the default of whole module means most developers need never
use access control unless they desire to reduce access scope (e.g. file
scope, dec scoped). Those working on frameworks would be the ones to
leverage public in addition to the other levels.

Of the top of my head: ` pubic`, `internal` (and `internal(module`)),
`internal(file)`, `private`. This makes public and private being closest to
other languages as you noted with internal being more swift nuanced.
