What's the motivations behind the Python language add-ons ?
I think the first motivation is to make the code more *concise*.
+ For decorators, the first use case was the ability to provide a
concise way to tell that a function is a classmethod or a
staticmethod.
(ie: == add meta info or code on a function)
Many use cases exists now as well (memoizing, type checking, etc..)
and some of them can fit for Zope use cases as well.
+ For genexps, they are a concise way of writing iterators, as they
use list comprehension syntax.
(Besides that point, there's a module that's very handy to write
iterators: itertools it's also very very fast)
+ reversed() also provide a simple way to do a backward loop
And it's also a bit faster. But yes, decorators are the most
interesting feature, with generator expressions.
As well, does Zope-2.8.x runs against 2.4.2 and has it been announced
security compliant on Zope-2.8.x ?
Yes, Jim did the necessary changes and the result is in Zope 2.8.4.
