In Zope 2.7 and before, ExtensionClass methods were magic objects.

  When you used "method.attr", then the method actually
  used "getattr(method.im_self, method.im_func.func_name+'attr')"
  to retrieve "attr" (i.e. "attr" where retrieved from the bound

For the new style ExtensionClass implementation
(used from Zope 2.8 on), Jim removed this magic.

You can use the "getattr" above to resolve the attribute.
