I believe (though you'll want to test this out) that an unqualified __file__ refers to the file of
the currently executing module -- in other words, it's just like any other module-global attribute,
requiring qualification when you're looking for the attribute belonging to an outside (imported)
module.  However, I haven't tested this recently, so I could be mistaken.  :)
