I was forced to use proxies because of annoying limitations in Python's module implementation and the inspect module's assumption that a module is not a module unless it subclasses the standard Python module type. I expect though that a simpler proxy implementation could be used by deferredimport. This would make zope.component depend on zope.proxy only if the annoying zcml is used.

A little investigation shows me that Jim is correct. 1. zope.interface 'just works' as pure-python 2. zope.component depends on zope.proxy: a. in zcml.py. (I probably wouldn't be using zcml in my experiment) b. by its dependency on zope.deferredimport If I have understood the code correctly in zope.deferredimport the problem which zope.proxy.ProxyBase answers is in the following snippet from z.deferredimport.deferredmodule:initialize  where a type(module) comparison is made. Therefore, if I could understand fully Jim's statement: "the inspect module's assumption that a module is not a module unless it subclasses the standard Python module type" Then I could attempt to substitute pure-python code for the type(module) problem which appears in the `initialize` method.
