wherever you like :)

Does you compiler report anything?

That's the point. Pack1 is generic, it is not an instance.
By writing Some_Package.Something_Else, you are referring
to Something_Else in a real package (which can be a plain
package, or an real instance of a generic package).
Imagine you had a generic package as before,
with a nested generic. But the formal parameter of the
nested generic is different from the formal parameter of
the outer package.
The outer is instantiated with some actual type. What have
you got?
