D'oh.  You're correct, of course.

What I was thinking was along the lines of:

--> some_table = Path('~/addresses.dbf')
--> some_table = os.path.expanduser(some_table)

vs


--> some_table = Path('~/addresses.dbf')
--> some_table = Path(os.path.expanduser(str(some_table)))

The Path/str sandwich is ackward, as well as verbose.
