Raymond, it's a good question.

I have added `name` to `property` constructor to support cases when a property is added to a class after it was declared.

For instance:

```
class Foo:
    pass


Foo.foo = property(name='foo')

f = Foo()
f.foo = 10
```

So, in my opinion, it's expected behavior that `name` is overwritten by `__set_name__` method.

What do you think about that? Should we change this behevior?
