[Zope] Class Refactoring Question

[James W. Howe]

I've developed a couple of simply Python classes which I'm using as base 
classes for some ZClasses that I've developed.  I now realize that both of 
these Python classes could benefit from obtaining behavior from another 
class.  Will I complete hose myself if I change the class definition of my 
Python base classes?  In other words, will existing ZClass instances be 
completely screwed up if I do this?

For example, suppose that I have a base class written in Python which looks 
like this:

class MyFolder(OFS.Folder.Folder):
     ...

I have a ZClass which uses MyFolder as a base, and I have one or more 
instances of my ZClass in my ZODB.

I would like to change the definition of MyFolder to be something like this:

class MyFolder(OFS.Folder.Folder, SomeOtherClass):
     ...

Can I do this, or am I asking for trouble.

Thanks.
