Re: Examples of Pojo Free Code?

George - we agree. Here's how I think of discipline. Most people have only
80-100 units at one time, asking them not to use Setter's or Classes that
Eclipse helpful pops up might cost 10 units. I would rather use those 10
units on practicing TDD without outside help in the months after taking a
course from me :-)

If it helps George many people don't realize how unique you're - you might
have 250 units of discipline at one time. However your world is not the
world of others.

Cheers
Mark
