When I originally proposed properties a long time ago in the mailing list
this is exactly what I proposed.  You can check the archives.  I think it
turned out to be too simple too implement.   You can either check the
archives for the old discussion or you can try to work out the details for
yourself.   I may be wrong but it didn't work for me when I went through the
exercise before.

BTW: super doesn't do what you want here.  super works with prototype links,
not attribute ownership.  That is why my proto implementation makes "self"
point to the attribute owner (Proto1).   This way you can just say self.x to
get to that level.
