[Zope] ZClasses vs. Python Products

[Paul Winkler]

Just to comment on a couple of your issues, I don't know about
all of them...

First of all, the "__setstate__()" tip they mention is pretty easy
and will update all existing objects.

Secondly, __setstate__() is only necessary for *data* attributes; 
methods are automatically updated when the Product code is loaded, e.g.
when Zope starts.

Thirdly, you can force Product code to reload by using the
Refresh product. Saves a *lot* of time vs. restarting Zope
every time you want to check some changes.

Yes, but it's a bit hobbled. 
See e.g. the Advanced Scripting chapter of the Zope Book:
http://www.zope.org/Documentation/ZopeBook/ScriptingZope.stx
... the section "Security Restrictions".

Code in Python Products can do *anything*.
