The "with" confuses me because I am not sure specifically what happens
in the context manager. I'm taking it for granted in this case that
__exit__() closes the file?
I am finding many examples of file handling using the context manager,
but none so far that wrap into a generator; more often and file object.
Is there a preference for file object over generator?
