My view is that declarations should always contain the fully-qualified
type if it comes from a package that you had to with, even if you've
used the package; in other words, don't 'use' until the end of a
declarative region. Saves a vast amount of grief finding where things
come (I know that GNAT will often retain enough context after a failed
compilation for browsing to work, but it's just so much easier for the
writer to tell the reader where stuff is supposed to come from!)

Exceptions:
   Ada.Text_IO
   Packages in a hierarchy
