Here is one programming process approach that often simplifies these
questions: Write the Bar unit tests in parallel with designing Bar.

If the Bar design works well for both unit testing and use by a Foo,
it will probably be a reasonably robust module that does not need to
be changed too often because of changes to other modules.
