But my attributes are not normal. So I should generate them by
__getattr__. Only by noticing that I could get the same effect by
putting my attribute source in front of my object in the acquisition
The question is still, how does one a __getattr__ that needs (as a
client) acquisition to calculate the attribute.
(Basically __of__ works only if I do not need to know the attribute name
and do not mind a changed acquisition chain, __getattr__ works only if I
do not need Acquisition, ...)

Well, where else can I patch it in?
