My example shows this more clearly I think:

   def read_config(path):
       text = path.open().read()
       ... do something ...

If I implement a URI object with an .open() method, then I can use it 
with this function, even though read_config() was written with file 
paths in mind.  But without it that won't work:

   def read_config(path):
       text = open(path).read()
       ...
