From Objects to Functions: (B7.0) Zettai class doesn't have referenced getTodoList() method (page 34)

@uberto
On page 34 in “Designing with Arrows” we reference to getToDoList() of the Zettai class in fact we defined on page 32 a showList() method. At that point in time the only getToDoList() exists in our acceptance test.

This is the page where I gave up. It is very frustrating that the text frequently mentions code that doesn’t exist, and trying to dig it out of the provided source code which doesn’t match the state of the code as discussed in the text to that point doesn’t make following along any easier.

If the intent is to get the user to follow along with the dev process - a style I live very much - the writing needs to make sense from the point of view of a user typing it in. It does not.
