I'm not sure what you mean.  The idea is to provide a pure-python  
implementation of ModuleProxy.  ModuleProxy doesn't have to be as  
complete as zope.proxy allows.  The need for a proxy is due to the  
inspect module's use of isinstance.  isinstance in turn uses an  
object's __class__ attribute, which a proxy can override.

I hope this hint helps.
