== Why is this an issue?

The access level defaults to ``++internal++`` if left unspecified. Since that doesn't make sense for most top-level declarations, access levels should always be specified explicitly, even when ``++internal++`` is what's intended.


This rule raises an issue when the access level is not specified on any top-level declaration.
