And how do I return an attribute that is acquired (but not down th main
acquisition path, but on a side line?)
I assume that I could probably play some silly games with __of__ to make
my additional Acquisition objects to come just before my object in the
acquisition path, ...
But still it seems to me, it could be nice if __getattr__ would be
called on an explicit wrapper of self, instead of the direct pure self.
