Hi everyone, in an effort to bring zope.container to PyPy, I was trying to port zope.container. Unfortunately, it defines a ContainedProxy, which inherits from zope.security's PyProxyBase and persistent's ProxyPy. Since both of those proxies have slots defined, they cannot both be base classes for the ContainedProxy. So what should I do? I could split the existing classes like so, but it seems ugly: class BaseProxyPy(object): ... class ProxyPy(BaseProxyPy) __slots__ = ('_wrapped',) Jim, Tres, any ideas/comments?
