This does not work because Python calls "__getattr__" only,
if it can not find the attribute through "normal" means.
Due to the implementation of "Acquisition", acquired attributes
are found by "normal" means bypassing "__getattr__".
You may be successful, if you override "__of__".
It is this method that (usually) builds the acquisition wrapper.
You can try to build an explicit rather than implicit acquisition
The easiest way, of course, is to derive the class from
"Acquisition.Explicit" with higher priority (more to the left)
than from "Acquisition.Implicit".
