Thanks, I knew the possibility of using another level of indirection
vir explicit __set and __get methods but I haven't seen a solution
with lambda yet. I think on ActiveState's Python Cookbook site
there was a quite longish solution, too.

Then I formulate it more precisely: The "self" parameter is passed
to the setters and getters, however, it is not used for calling the
"correct" ones. "Correct" seems to be in the eye of the beholder:
The Python designers apparently intentionally chose this odd
"semi-static" behaviour of "property". But I think a fully virtual
behaviour would fit better into the Python mentality, it is easier
to explain, and it has more use cases.

Tschö,
Torsten.
