[Zope] New-style classes and PluggableBrains

[Jean-Francois.Doyon at CCRS.NRCan.gc.ca]

I do beleive new-style classes are not currently supported in Zope 2.7.x,
due to issues with ExtensionClass.

Zope 2.8 should do away with that issue, allowing you to use new-style
classes.

This, mind you, might not be applicable to you, as PluggableBrains might not
be wrapped by ExtensionClass??

I'm working on developing a PluggableBrains class for some SQL methods 
in my application in Zope 2.7.1 (running Python 2.3.3 as shipped in the 
Windows Zope installer), and I've got a couple quick questions.

First, if my class inherits from object, does that break anything? It's 
also inheriting from Acquisition.Implicit and has security information 
(as an external method creates one and passes it off to protected code 
in a place or two).

Second, if I have some property objects as members, will code accessing 
them elsewhere behave in a sane and reasonable manner? Will Zope 
recognize them properly? Most importantly, can I have some or all of 
the members that the Z SQL Method will be populating defined as 
properties in the class?

TIA,
Michael
