I believe that this should be changed, so that Python first looks for the attribute in the instance's dict and only then through the dict's mro. [snip] What do you think?

Are you suggesting that the following code should print "43" instead of "42"? :: >>> class C(object): ... x = property(lambda self: self._x) ... def init(self): ... self._x = 42 ... >>> c = C() >>> c.dict['x'] = 43 >>> c.x 42

If so, this is a pretty substantial backwards incompatibility, and you should probably post this to python-ideas first to hash things out. If people like it there, the right target is probably Python 3000, not Python 2.x.
