A spasm of Refactoring.

A spasm of refactoring in which we lost the video of the first tomato -- thankfully!

Yes, it's true. We lost the first tomato. Well, we didn't lose it. We just forgot to hit the record button.

Well, we think we did anyway. It's kind of hard to tell. You'll see. But Justin does a nice job showing you how to do it.


Anyway, we got down to business in the second tomato by removing all the horrible exceptions and replacing them with tuple-based error returns. As it turns out, this worked pretty well.
