The qualified names (Blah.foo, Blah.baz) are in scope, but not the unqualified names foo, 
baz.

If you 
import qualified Bing.Bong.Blah.Blub as Blub

the names of Blub are in scope in the fully qualified form

Bing.Bong.Blah.Blub.foo

and the shorter 

Blub.foo

without the 'as Blub', only the fully qualified form is in scope.
