Bug report

Bug description:

class A:
    @property
    def computed_a(self):
        return 2

    @property
    def computed_b(self):
        return 3
    @computed_b.setter
    def computed_b(self, val):
        print('set!')

a = A()
a.computed_a = 12 # typo

When running this, I would expect to get AttributeError: ... Did you mean: 'computed_b', but I'm not getting a suggestion. I think it's because the AttributeError that property.__set__ raises doesn't have .obj and .name set.
