possible while I'm at pycon and away from customers ... and
motivated ... etc.

I've done Zope2 stuff in the past, including writing Zope2 Products.
We are working on new hosting software and have decided to use
Zope 3.
So we're defining our interfaces and have started to define
classes based on those interfaces and I have a question...
The simple todo app (http://worldcookery.com/files/jeffshell-todo/
step1.html) shows the Todo class having three attributes
(description, details, done). These are all defined in the
interface using various zope.schema definitions.
But ...
The Boring product (http://products.nidelven-it.no/zope3_boring/)
does the same thing in the interface with a title attribute. But
when it gets to the class definition it uses:
def __init__(self, title='Default boring title'):
self.title = title
The later is more familiar to me coming from Zope 2. Which is
right? If they are both right, which is *more* right wrt Zope
3 ... and why?
They are both right, and it doesn't matter.
The interface says "when you have an instance of this object, you
can expect there to be a 'title' attribute". How it got there is
not that important.
By the way, if you're starting with Zope 3, get Philipp von
Weitershausen's book Web Component Development with Zope 3
(www.worldcookery.com). It'll make a lot of this stuff much more
clear.
