There are several mistaken replies here.
Library unit packages are at library level,
as are all their contents, both spec and body.
You only "leave" library level by going inside
a subprogram, a type, a generic, etc.
You *stay* at the same level when you enter a sub-package.
Accessibility level relates to "lifetime." The contents
of a package live as long as the package itself.
On the other hand, the declarations inside a subprogram
last only as long as any given *call* on the subprogram,
whereas the subprogram itself lasts as long as the enclosing
scope lives.
